Catch all term for anything along the lines of a jerk, douchebag, sleaze, chauvanist, ranging from playful usage to deliberate dissing. It can be used to indicate that a guy is of less worth than the average human being - literally - or as a tease.
Teasing: "Dude! What are you WEARING?! You look like such a chotch! (laughs)"
Dislike: "I F***ing hate that guy! He is SUCH a chotch! I just want to punch him in the face."
