Ypsilanti water tower

Something that has got to be the most phallic thing you ever saw.

“That thing is so phallic it might as well count as pornographic. Total Ypsilanti Water Tower.”

Ypsilanti All-Stars 

Publicized widely in the magazine "Found", the Yspsilanti All-Stars are a booty rap group from Ypsilanti, Michigan. A poorly-recorded copy of their 1998 demo was submitted to Found magazine, who later distributed it (illegally) as a CD called "The Booty Don't Stop". Notable song titles include "Wave Yo' Booty in the Air" and "It's Booty Time".

Ypsilanti All-Stars were bumping in the club all night long.

Having sex with nothing but a fanny pack on.

I went for a run and then went straight to the bedroom to give my wife an Ypsilanti Fanny.

YPSILANTI Uppercut 

County of origin: Sac and Fox

When attacking a lady friend from behind she mentions that you might be the smallest thing she’s had since junior high. You then proceed to give her a wicked awesome YPSILANTI Uppercut which is performed whilst yelling ‘YPSILANTI’ at the top of your lungs.

It differs from the donkey punch because you catch the chin as apposed to catching the base of the skull. Different style concussion, a different style of Stall0wnage.

Teh kicker: You probably are the smallest thing she’s had since junior high, but who’s on top and who’s on bottom now!

Thirdly: You can leave the room with out the awkward look of shame that most women have given you over the years

When Wanda insulted my manhood, I gave her a swift YPSILANTI Uppercut, drank her Crystal Light and left her on the bathroom floor to think about what she had done wrong.
