Alpha male- "Dude, thanks for being my wingman, sorry about that grenade knee."
Beta male- "Okay, Bro, but next time you get the grenade knee."
Alpha male *under his breath* "Yeah, right."

A game played by children, as well as teens, where all players hold a small hockey stick that is the appropriate length to use when on one's knees. It is ideally played full contact, but leaving one's knees is a violation of the rules. It is an Americanized version of the Canadian game {{mini-sticks}}, and is commonly played in basements across the Midwest, New England, the Mid-Atlantic and throughout the United States.
At out of town youth hockey tournaments, players often bring small nets and sticks so they can play knee hockey in the hotel hallways.

Bopper knees are the bruised knees of a bitch that sucks on cock for money or anything of value. Bopper knees do not discriminate. They can be on a hoe suckin dick to get on a private jet, or they can be on a skeezer suckin dick for a bag of used DVD movies.
