Something or someone that's just a big ol' bunch of nothing but total fuck. Someone who is both an idiot and mean, at the same time. Can be shortened to "fwad".
Jesse always gives all the new employees a really hard time because he knows he can get most of them to quit. He's a real fuck wad (fwad).
After we got done humping the hell out of each other, neither one of us wanted to feel the cold fuck wad on our backs. So we both slept on our sides.
I couldn't believe the number of fuck wads my guests left on my spare bed!
