A girl who does not use daily cleansing habits would have a RAUNCHY CHAUNCHY.
Sandy: "Ew that girl smells like shit her raunchy chaunchy is exploding she is so DIRTY it is dripping on the floor...her chunky monkey is stinking up the room."
Dina: "Damn Poochie Coochie!....Clean up yo raunchy chaunchy!"
To violently jerk off and "launch" a load after doing a bunch of coke. A portmanteau for "coke launch".
Whisper it to yourself. "Claaaauuunnnnch"
The poor guy was a degenerate. A depressed and high strung individual and addicted to porn, he regularly sniffs coke and locks himself in his room and masturbates. Claunching hard.
