After life fucked somebody up, to help them get better mentally by having sex with them. Typically also implies the person is a bottom, meaning one literally goes down on them while fucking.
Man I'm so fucked up, hopefully this new girl I'm dating will finally fuck me back down...
To fuck someone back down should be a cultural norm in today's society where so many people are lonely and depressed
Sadly, no one like this exists. The shit you just said is understood by 0.00001% of people, a.k.a. you. Also, 0.00001% of people give a fuck, thus proving my point. If I were you I would suggest trying to get some friends you absolute loner. Also, congratulations. You have just got a world record. You got it for having no one give a fuck about what you said. Bravo👏.
