On-Deck Switch Hitter. Someone who is heterosexual, but who fantasizes about having a homosexual experience. Pronounced "oddsh."
"You know, Jim, I'm sure I'm 100% straight, but the girl-on-girl action in that porn film we watched the other day kinda turned me on."
"Well, maybe you're an ODSH."
"A what?"
"An on-deck switch hitter."
"Well, I don't know. I didn't think so before."
"Your friend Cathy's a switch hitter. Why not give her a try?"
"I don't know; that'd be kinda weird. I'd have to think about it."
