Little Saturday

Turkish Saturday

A little known hangover remedy consisting of Turkish coffee and heavy cream mixed with spirits (preferrably a trace amount of vodka). Generally consumed the morning after.

I was feeling like crap the next day until my buddy mixed me up a Turkish Saturday.

Semen Saturday 

The act of catching your nut and making the sign of the cross on the female’s forehead as if you were a priest on Ash Wednesday

Deborah was very religious, and missed church that week so she told Kyle, “That was some great sex, but did you remember to give me the Semen Saturday?”

Sleeveless Saturday

Sleeveless Saturday is a time honored Georgetown University tradition that has been going on for almost seven years. The tradition gets passed down from seniors to freshmen or sophomores that deserve the right to throw the sickest parties on campus. The parties involve waking up before 10:00 am and drinking all day until night activities take over. Sleeves are not allowed and if someone walks in with sleeves on they are immediately ripped off by one of the party hosts. Creative sleeveless tops have included bullet proof vests, life jackets, sleeveless maintenance jumpsuits, sleeveless blazers, and sleeveless animal costumes.

Dude I got so drunk at sleeveless saturday that I wound up pissing my roommates bed before waking up next to his girlfriend.
