ugly sister competition

Being offered the choice between bad and worse.

"The salvation of the pound is that its problem is not a pound-specific problem," he said. "It's an ugly sister competition and at the moment we're looking the ugliest. But if you sell the pound, what will you buy?" (The New York Times, Jan. 21st, 2009)

your sisters penis

Almost as good as your moms cock but not quite! It’s more slimy but it’s a little smaller! The one thing though is it’s fatter than your moms cock!

Your sisters penis was so nice last night. Uahhhh
