Mr. Personality 

a term used to describe a male who presents stellar wit and persona but is ugly, fat, or in general - undesirable for sex. They usually end up in the "friend zone."

The origin is a song called "Mr. Personality" by 20 Fingers. A pseudo one-hit wonder.

CHORUS:
they call you mr personality because you're so ugly
they call you mr personality because you're so ugly
you're so ugly
mr personality, you're so ugly
mr personality, you're so ugly
mr personality, you're so ugly

when i look at you i go outta my mind,
its like im lookin at someones behind.
you make the children scream and babys cry,
with your crusty teeth and your bloodshot eyes.
you're so ugly, your dad hadda tie a porkchop around your neck just to get the dog to play witcha
ooh thats ugly.

Mr. Personality 

When you are dumb-dumb, and are devoid of personality

Instead of picking up all of the trash scattered around his property, Mr. Personality sprayed it all with a hose, like a real yutz.
