bumping uglies

"Bumping Uglies" is when two unattractive people are copulating, and, the average person would be repulsed to witness such an act.
Of course the word 'unattractive' is really a relative concept isn't it.

God, I can't imagine my parents "doing it", they're a couple of 'bumping uglies'.
