saying "dead as fuck" means youre at an emotional coma. basically its when you get to a point of laughter or shock that you really have nothing else you can do or say, so you just kinda sit there lifeless - or dead. mostly used on the internet but it works around friends too.

When proceeding to have sexual intercourse with the opposite sex, your partner appears to die. Foreplay can be very active and passionate, but once the penis is inserted into the women she becomes incapacitated.

When having sex with a female, she preceeds to lay there motionless and just stare you in the eyes. No emotion whatsoever. Doesn't appear to be interested in the physical happenings of the moment. Alive, but resembling a dead body by her lack of movement.
Heather White was the gnarliest dead fuck I ever had, she never moved or got into it.

When you're attempting to fuck a male who expects you to initiate every time. A male Chris who just lays on his back and expects to get a nut that he hasn't earned. A male who wants head but is to lazy to get off his ass and give his girl head. A dead fuck lays there and expects the girl to get on top. A dead fuck doesn't do shit. Expects the girl to do all the work but gives no pleasure in return.
Chris is a dead fuck, he just lays there.

No one wants to be with that dead fuck Chris, he's so lazy in bed.
