An activity where you stick your male member gets stuck in a bucks mouth after shooting a puck up a buck's ass. usually is the last thing on someone's bucket list.
"wow dude I just went buckfutting and the buckbit off my penis"
when a guy and a girl put their hands and feet together while standing in the form of brackets, but the guy has a long enough dick to have sex with her in the process. then when he has to ejaculate he pulls out and smacks her in the fucking face with it. viagra or cialis is common for this move.
carm:"hey rick what did you do last night"?
rick: i was fucking bracketting this bitch last night.. i left a mark on her forhead.
carm: "oh.. kickass!"
A bit of a more uncommon example, but also works. The act of fucking someone with your nuts in their ass, usually a guy.
Y:seems like you got a lot of repressed emotions going on over there
M:only repressed emotions here are yours. i know how bad you dream of me chicken bucketing you. gtfo.
