Blowjob choke
when a guy's getting a blowjob from a girl/guy and pushes his penis so far down the blowjob giver's throat that they choke, occasionally resulting in the poor girl/guy throwing up.
"Damn it, Nathan made me blowjob choke the other night, i nearly vomited! Dude his cock's way to big for me to go deep throat on him!"
