When going up for a dunk and the ball slips out of your hands or you misjudge the jump and it ends up bouncing around sloppily before going in. Derived in 2006 in Muscatine, Iowa by combining layup and dunk.
Kobe went to throw down but couldn't finish and ended up lunking it instead. Garrett can't dunk but lunks like a champion.

deriving from a magical chat on the 29th of February, 2012. Originally, it was a spelling mistake for luck, but it has magically caught on in the Hustler/Lunker fanbase. We say that Lunk is another term for a penis, but you can really just put Lunk in to replace anything.

Join the Lunker Gang.
"Good lunk!"

That crappy gunk you get in your lungs when you smoke ciagrettes. It paralyzes the silia in your lungs so they can't filter the crap out and it makes it hard to breathe.
"Hey, Amanda, let's go to the movies tonight"

"Oh, it must be the lunk kicking in, i guess I must find anoher friend to go with"
