Over-The-Pants-Hand-Job. Distant cousin of the dry hump.

The smell that radiates off of a whore. Ususaly caused by resisting to clean mixed with STD's. Like pulling a whole weekend of nonstop Halo whilst stewing in your own masterbation filth and microwaveable foods.

The shape and hygiene of a woman's lips whilst giving a blow job.
