The world's full of whiny, effeminate guys who piss everyone off.
We'd love to punch them all in their stupid faces, but that would be wrong. I guess.
So why not send one of 'em you know a tampon instead?
It can be your clever way of letting them know how much of a pussy you think they are.
And it's sure to upset them, which would be a nice change of pace, wouldn't it?
Oh, and if you'd like, we can include a dirty, hand-written note along with it... you know, just in case they're too stupid to understand the symbolism of the tampon.
