From my friend:

Alright.

The Thong Theory.

1) Who would want to wear something where the material is equal to two rubber bands and a tissue?

2) Who would want to wear something that could also be called butt floss?

3) It's so much fun to use as a slingshot!

For guys, it's called a jock strap, but it has a cup in it.

(Please ignore this one if you find it offensive. I just thought she was right, that's all, though I wouldn't normally think much on the subject.)
