The term "Cameltoe Slide". It's something I've done for a while, but never had a name for it. It's when the penis is slid back and forth between the labia and over the clit. It can be done by the guy or by the girl (she can "ride" him but slide on him instead of having him penetrate).
Troll is derived from fisherman terminology. Trolling means dangling your fishing line behind your boat as it moves through the water. Next the fish follow the bate. So Internet trolling is essentially bating people to respond to your postings with anger, annoyance, defensively, or stirring up a flame war in the forums. Hence its name.
That sais I probably learned a few terms here.
But the only one I can think of right now is Spank Bank
'Butt hurt' immediately comes to mind besides the likes of 'brb', 'lmfao' or 'lol'. At the time I had joined this site over four years ago, I wasn't even aware of the existence of such words. And I rarely use the terms if at all.
