underground railroad

the act of getting a girl drunk and bringing her back to your hotel room, where 4-6 of your friends are waiting in the bathroom. Proceed to slam her from behind, (its key to make sure she cant see your face) and when you are about finished, you call in the next guy. This secret train continues until all 4-6 are finished. When the caboose is done, u go back to the girl, fake an orgasm, and your done with her. Make sure she leaves the hotel room quick, before she wants to use the bathroom.

After the game me and half the team are planning on getting an underground railroad going on some skank from the club, you want in?

Underground Air Raid

A pure racist and/or rapist. Its like eating an Indian, Japanesse, Thai, Mexican burrito while hungover packed with gummy worms, spoiled beans and marsh mellows that are 3years past the expiration date. Vomit inducer.....Look up the definition of "Air Raid" and let your imagination flow. Ever wish you had that magic "wand" that makes everything disappear? Well that would come in handy in an Underground Air Raid....

Best pal Randy says " Here you are little girl...another beer?"
Lindsay-"I just had one beer who wants to do me?!?!!!Opps, I have HIV! But OH well!!!"
Fred-"I am so ready to have sex with you!!"
Lindsay-"Sounds great! Like OMG!"
Fred- "I would like to introduce the underground air raid...mmmhhhmmm"
Best pal Randy says "Don't sink in, we may not see you EVER again...not a big loss anyways, just sayin."
Fred- "Sweetheart I never got your name"
