The act of informally asking someone to suck one's genitals to the brink of dryness. Mostly served for males and is considered a deep throat or fellatio.
"It's literally suck me dry. Goddamn it why go to Urban Dictionary you idiot."
1.) To give fellatio until one is to run dry of semen.
2.) Used interjectionally without knowing the meaning by the mind-controlling alien in Aqua Teen Hunger Force after he learned it from one of Carls talk-nasty tapes. Then later said at his own will after a job interview.
interviewer: Okay, well when we start hiring.. animals or whatever.. we'll give you a call.
alien: suck it dry!
