This word is used to describe a girl who takes being a bitch to a whole new level. Although the regular word to describe this kind of girl is "megabitch," this particular girl is the leader of a group of
bitches (who can be referred to as bitchcepticons.) The word is derived from the
words "
megatron" (the leader of the the decepticons in transformers), and "megabitch."
Guy: "Oh that girl is such a bitch, and it's only because she has a big
ass!"
Girl: "I know! She's a megabitchron! I
hate her and her bitchcepticons!"
