A medlock is a big boobed mangina. He/she likes to suck the end of a horses falice. Whilst sitting and reciting Fantastic Mr Fox to himself at home, he has female slave weasels suck upon his juicy moobs. Opening park gates turns him on.
Also, he likes to suck air out of television speakers and polished dishwashers with his tongue.
Boy: Hey look at that boy/girl over there who has boobs, sucking on a falice, reciting fantastic mr fox with weasels sucking upon his nipples, wanking over that gate, sucking that speaker and licking that polished dishwasher!
Girl: Yeah! He's such a Medlock.
