Fuck you chill

Fucking someone that is always stressed out so that afterwords is “chill”.

Having intercourse with a person that is always on the edge so that person can finally relax.

“You really needed someone that fuck you chill on the regular, you were always so tense”

“You have been so relaxed lately, I’m glad your new boyfriend fuck you chill every day now”

“You’re such a crazy bitch, I’m going to fuck you chill real good”
