BP

A bp is the abbreviated way of saying "Bush Pig". This is typically used when you see a fat female who is an extreme bogan or redneck that is not at all desirable. Someone that typically not city folk and lives in the outer suburbs. They're easy to tell because they're usually loud mouthed "animal" like creatures. The last thing you want is to be seen near BPs when you go out as it sends a signals to other women that you're undesirable.
