November 14: Weiner Cousins

When two men have had sex with the same woman/women, they become weiner cousins. This is a bond that can never be broken.

We’re weiner cousins now, that means we’re closer than brothers.

Heh heh.  Good one.  They don’t mention if it has to happen at the same time.  I suppose not.  But that IS immediately what came to mind.
