0% oxygen still rapping Oxygen : wait, thats illegal

I watch this while enjoying my delicious oxygen.

Mac: *Raps 77 seconds* "DOH" Me: *Raps 7 seconds* "DOH"

"breathing technique makes you hallucinate." Well I know what I'm trying tonight

Rapping for 77 seconds is not a joke bro .

Mac lethal: wanna hear a joke? Me: ofc Mac lethal: *oxygen*

Are we just going to ignore that his rap was absolutely fire

Teacher: all living things need oxygen to live. Mac: no.

Oxygen: am I a joke to you?

Mac: raps for 77 seconds Oxygen: "cries" so you don't need me anymore?"

Damn just watching this made me feel like I was losing breath. At the end there Mac looked really disappointed and I feel bad, I trust that one day he’ll be able to master 90s or even more. You never seize to amaze us bro!

It's hard to believe the things humans can do sometimes... This was awesome.

"You try it" Bold of you to assume I can rap.

Eminem: Rap god Mac Lethal: Hold my oxygen.

I hold my breathe with him cz i was so impressed

77 seconds is very good lemme call in Eminem to see if he could win

I want to push the limits of rap. Physically, mentally and creatively. Give me ideas for the next video. Rap in multiple languages? Rap while grilling a steak? Rap while doing origami? What about rap my entire life story with photos of my life? Give me ideas?!

Oxygen : * Left the chat*

HOLY CRAP! HE IS SOOO GOOD!!! I GIVE HIM 5 STARS... A MUST SEE! I actually held my breath the whole time he held his breath to rap...it wasn't easy and imagine he was rapping at the same time! my hat goes off to him.

Rap starts at 3:31 for the people that can’t wait

Literally any other human: "I got 20 seconds! Mac Lethal: "Ugh, only 77.."

anyone breathe a bunch while he was rapping

I got my grandma to try this and she was vibing so much she is dancing on the floor

Imagine being sad cuz you can only rap for 77 seconds without breathing wtf

If he mumbled rap he could go for 10mins bhahahaha

THAT WAS IMPRESSIVE!!! 77 is still a VERY long time!! 👏👏

Don't be so hard on yourself, honestly i was already impressed with 20 seconds

Mac Lethal: holds his breath and rap’s for 77 seconds Me: can’t even hold my breath for 10 seconds

0% money 0% strippers 0% oxygen 100% talent sorry had to do it to em.

Make a backwards alphabet insanity. So start at z and go to a

Verse 1] I just wanna rap for 90 seconds without breathing Here we go I'm gonna try it hopefully I won't be screaming By the end of it I cannot take a single breath man not even a little bit I hope this ain't a target that I didn't hit And all these rappers out right now are faker than an Instagram booty I'm like a Jedi when I rap I shoulda been in a movie You gotta understand a couple things about me I'm a Kansas City native and I'm busting hella rowdy Got a house up in the hills I got a castle where I chill I'm always working on my raps and always practising this skill And you should never sleep on me like I'm a cactus in your pillow Hear the instrumental then I kick a track out with a steel toe Everybody listening to all this mumble rap is terrible You open up my brain I bet it is 24-carat gold You know that when I rap it's hella dope sit hear the vibes your on my UKposts channel now oh man I hope you will subscribe so look Somebody tried to say that when you're living underwater it's impossible to breathe and I just gotta disagree Cause when I'm rapping not a single bit of oxygen is sitting in my lungs and I'm relaxing at the bottom of the sea You see my wife and I were riding in the car today and started fighting And I just left her walked into the studio and started writing I decided that I was gonna rap without a single breath And never did it bring my death But fuck it it would be refreshing I am a believer in the universe's sorrow I just wish that I could move away to Jupiter tomorrow Time and time again I sit around I'm patiently just waiting for the weekend 20,000 years ago I was a pharaoh back in Egypt with a coat of gold and feathers and a crown of thorns See I invented thunderstorms and all the ways that clouds could form See I was born abused as ginger going to the kingdom of the science and my mother was a singer to the sciences I navigate the globe they call me leader to the lions And my wings are made of fire I'ma bring you to the tiger I'ma feed you to a tiger motherfucker I cannot breathe I'm forgetting the lyrics anybody gonna try to leave I gotta try to mumble now I gotta do a freestyle Everybody knows that I'm gonna get a little senile One-fifteen one-sixteen ARGH!

You kill it man hat's off you 🔥🙌

Nena: 99 red ballons Mac lethal: 99 lungs

Ok ninja... You said you can do a lot of push-ups?... Rap one of your own songs, in it's entirety, while doing push-ups the whole song... That would be cool!

Damnn the perseverance is inspiring bro🙏🏼

WOW 😳😲😲😲😲🔥🔥🔥 How is you I'm speechless... You are so brilliant

2019 Mac: I rapped for 90 seconds without breathing 2119 Mac: I went to the moon rapping and got back without a spacesuit.

rap starts at 3:30

thats still super sick bro thats friggen hell yeah

Incredible. Bro.. Dope

Oxygen=Hello?? Do u even need me Mac lethal=U are a joke for me

People: How long can you rap? Mac Lethal: *yes*

This was an amazing attempt. If you just started that day working on a new breathing technique, I wonder if your lung capacity would grow if you performed that technique regularly. I think you can get to 90 seconds with some work, honestly.

i was getting lightheaded watching, incredible stuff o-o

To push for the last 30 seconds you should probably resist from shaking/moving you arm and also not hold a timer in the other arm. Both of these will reduce the consumption of the oxygen in your blood. I'm sure there are others way to cut it down also.

Bro I give u props u did awesome I started having a anxiety attack for u so Nice job!!!!

Nice work! Impressive

wow... you're awesome man. you can rap in a 4 bars music without breathing. you're a monster dude

2:23 i subscribed 😂😂 this dude is a legend

*Imagine he forgot to turn on the camera*
