I found this on YouTube. It's a group of Mexican guys in the car and the one in the passenger seat has to piss so bad he's shifting in his seat and grabbing his crotch. I'll put some translations of the best moments below:
0:19 - Passenger: F*ck, turn green already, damn it!
0:22 - Driver: It's red, idiot, what the f*ck do you want me to do?
0:25 - Passenger: Dude, I really have to piss.
0:29 - Passenger: [I'll have to] let it out into a bottle.
Back seat passenger: Look, look, look.
Passenger: What? Where?
(The guy in the back seat taunts him with a yogurt bottle, which is definitely too small to contain the monster piss he's holding inside his bladder.)
0:40 - Driver: Look, dude! The light still isn't turning f*cking green—
Passenger: F*ck, squeeze it, idiot!
0:47 - Passenger: Come on, I can't hold it anymore, okay?
Back seat passenger: Where are you ticklish?
When the light turns green, he calls the guy an asshole and mutters on about how bad he has to piss. At the very end you can hear him starting to say "Seven minutes" and then the video cuts off, so I can assume they were only seven minutes away from their destination? I wonder whether he was able to hold it until then.
