Swampthing 

When a gentleman lays down in a tub and has multiple men come in and ejaculate all over him. He then rises from the tub looking like swampthing

Swampthang

Ugly woman who wears revealing clothing with out revealing anything you'd want to see. Most likely to be seen at swimming pools, beaches, or any place where people are gathered in the summer months.
Swampthang's have no discernible breasts, or they have saggy, wrinkled breasts. Stick thin legs and arms, no butts, and faces that look like rawhide.

No dear, its just a Swampthang.
