A wicked twister is the act when a male drives his fist into the females vagina or anus and begins "wickedly twisting"
Me: hey Tyler
Tyler: ya ?
Me: I gave my girl a wicked twister last night
Tyler: I bet her clit looks like a dibble dong from all that twisting
When a girls clitoris looks as if a man's scrotum has been chopped off and sewn onto it
Me: Bro, see that chick right there
Guy: ya
Me: I went dowe on her once and she has the biggest dibble dong
Guy: gross man
