1.
HMG
Horny Mexican Guy
These guys are everywhere- sides of the roads, in your house, and even staring at you in the shower. Occasionally you can spot them on the sidewalk scratching their crotch vigorously.
Girl- "Ew that guy keeps staring at me."
Guy- "Don't flatter yourself, honey. That's just an HMG. They'll stare at anything."
