rally cap 

To wear one's baseball cap turned inside out and often sideways to encourage a rally from your favorite baseball team. Must be performed in the confines of a sporting facility and works best in the late innings of a game with runners on base.

The Yankees were down by one run in the bottom of the ninth so i rocked my rally cap.

When you put a condom on before you go out partying, because you know you'll forget at the end of the night, after all the boozin.

"Why the fuck do you already have a condom on Blake?"
"dont worry about it girl, i call this shit my Rally Cap. I put it on before going to the bars, because i always forget too when having drunk sex"

Getting head, blowing load across her forehead, then giving her a reverse Roman soldier and ass hat; while both chanting exuberantly, "Rally! Rally!"

My team was losing in the bottom of the 8th, so I took my girlfriend in the back room and gave her a Scranton rally cap.
