A highly insulting, yet quick way to tell someone you heavily dislike them. It implies that their mother is a homosexual woman, obviously I have yet to know when this phrase begun but all I do know is that this isn't a term you should take lightly. It is also a phrase highly meme'd upon, and I still have yet to figure out why the phrase is taken with humour.
