look up any word, like fleek:
A male penis that feels so good to a female during sex that her body goes into convulsions as if possessed by a demonic spirit.
Peep 1: Hey, did you take that black guy home last night?
Peep 2: Yeah girl, we got it on and he made me cum uncontrollably like 20 or 30 times....I lost control!
Peep 1: Damn, sounds like he put dat demon dick on you!
