look up any word, like slope:
 
1.
(v.) To sleep with a different woman than the one you slept with the night before, often more than once. Orginates from the

horndog character Jason Stackhouse on HBO's hit TV series True Blood. Stackhousing is done by people not in serious

relationships, and not to be confused with cheating.

Jon: So how'd the other night go with Molly?

Jim: That went fine, but I totally Stackhoused it and slept with Sarah last night, and that was even better!

Alex: It's not cheating, it's Stackhousing!
