A knee afflicted with inflammatory arthritis.
Shaun: Holy Shit, what's that Rick?
Rick: That'd just be my Boulder-Knee son.
A term stemming from a CU Boulder student's frustration with unpunished party fowls.
Anyone who commits a party fowl is required to get on one knee and shotgun a beer without delay. Any beer will do, but the cheaper/shittier the better. This is the only acceptable action to make up for spilling beer, not finishing a shot, or other fowls designated by the providers of the liquor and/or head(s) of the house/venue.
Self-administered penalty shotguns are not only acceptable but encouraged. Refusal of a penalty shotgun results in immediate removal from the party and well deserved embarrassment
A freshman walks into your party asks for a shot of Takaa Liquor (vodka or gin) and fails to take the entire shot:
"Ohhhh, you bitch! Penalty shotgun, right here ladies and gentlemen, he can't even finish a single shot! Someone get me a Keystone Light right now! Ok, take a knee you cocksucker, this is your one and only chance for redemption"
When a woman takes the gonads/nuts/testies of a man she is very fond of and gorilla glues each nut to the corresponding thigh and then breaks his knee caps causing to fall into a horizontal split position thus causing his nutsack to be ripped in half.
After pegging Johnny Appleseed, Maryellen started boulderfusing with him.
