1. Those kids who do backyard wrestling. Somehow throwing your best friend off the roof of his house equals fun for these assholes. The retard portion is just kind of implied since they thought this was a good idea in the first place.

2. The 1985 Chicago Bears for there rendition of the "Super Bowl Shuffle". Read the lyrics and you will agree. Some examples include "running the ball is like making romance", "I practice all day, dance all night", and of course "I run like lightnin', pass like thunder." If this is not the definition of asshole retard I don't know what is.

3. Anyone with a mullet.

4. Those guys who have "bumper balls" hanging from the trailer hitch of their truck. See bumperballs.com for plenty of examples.
