When something possibly sexual happens in a game of Dungeons & Dragons and the Dungeon Master wants to see if a character will pop a boner, or, if female, simply become aroused
"I want toflirt with the elf."
"She slaps you, roll a boner check."
"I rolled a 10."
"20, You get a boner."
PERSON1:i like it when you cum in my ass but i like it better when you tie your penis to a rope and pull on it like a puppeteer while your homies cum in my ass. you smell bad.
PERSON2:bone check motherfucker!
PERSON1 is now punched, kicked, stomped, and stabbed to death by PERSON2.
The act of open-hand swattage of the groin area on a guy coming towards you. If the person is guilty of boneage, then the force shoves the boner into the guy thus resulting in motionlessness, pain and pwnage.
guy 1: (coming towards you) "sup dude!"
guy 2: (you) "nuttin........BONE CHECK!!!" *swattage*
guy 1: awwwwwwwwwwwwwww............fag!
