Choinked is when you’re getting a blowjob and she is too toothy with it, and she scraped your mushroom tip with her teeth.
Glen: “Dude, I’ve had to free-ball now for 6 weeks ‘cause Stephany Choinked the fuck out my tip dog for real. Shit be more sore then a tube of preparation H.”
Kevin: “Dude, seriously, I hate when my tip gets Choinked so now I only get my top spun from bitches with no teeth. Feels like butter now and I haven’t been Choinked in 3 years. Feels good bro seriously.”
Choinch is anything and everything. This word can be used as a verb, adjective, noun, all of it. Such a word is not bogged down by futility of meaning.
