Big Fat Liar (Pronounced Like BIFFLE)

A BFL is a person who says just enough information that seems like a lie
but you can't call them out on it because you can't get adequate proof.

Bipolar Fat Lard. In other words, a PMS-ing male who is continually going through man-opause and is a fat lard who really has no point in existing in our world except for polluting the planet with his disgusting lardness.

Augh! You're such an irksome, annoying, obnoxious BFL!
