weiner step-bros

when you, being a man, have sex with a woman and a friend of yours, also being a man, has sex with that womans sister.
this is a life-long bond.

Tim fucked Sherry, and Bill fucked Sherry's sister, Jill.
Tim and Bill are weiner step-bros.
high five.

what are you doing step bro?

The question you ask when your step bro walks into your room with his big schlong dong out and about. Expect "Sweet Home Alabama," to start playing in the next few seconds.

Step Sis: *in a loli voice* What are you doing step bro? *bites her lip as she tugs on her skirt*

FBI Agent: Okay I have seen enough
