Swank The Tank 

A wanna be party boy trying to be like frank the tank from old school but is really nothing like it at all. Will usually go to a party and maybe sip a beer, then lie and say he is wasted.

A: "Dude im totally wasted right now!!"
B: "I saw you poor your first beer out in the sink. Your acting like Swank The Tank."

Stank in the Tank 

When your are at a party, Shit in the back of the toilet tank, so it always smells like someone just took a shit.(Usually isn't found for a couple days)

I was at this party and the persons toilet was clogged and I had to shit bad, It was either I shit in the toilet and left it for everyone to see, or Shit in the trash can and take it out, Fuck, I wasn't going to do either one of those, so I shit in the tank!!!! My friend called a plumber a few days later and that's what the plumber found,
The plumber called it the classic, "Stank in the Tank"
