Expresses the enjoyment of some particular occurrence, item, person, etc.
The two towels are used to soak up the ejaculate of the person doing the enjoying. (This is a figurative ejaculate and not a literal one, but it works either way) 1 Towel would usually be enough, but the extreme pleasure necessitates the use of 2 towels instead of 1.
Originated from an episode of "Drawn Together."
I can't believe Iron Maiden is performing tomorrow! I am going to need two towels!
