Tank and Flank 

Having sexual intercourse with a female and then promptly abandoning her.

She was looking for a long-term relationship, I just wanted to rail her. Needless to say, I pulled the ole' tank and flank and snuck out the back when she was sleeping.

when a person drinks a large quantity of alcohol and their alter ego emerges- the more drastic difference between the person and the alter ego, the more "frank the tank" they are- inspired by the movie old school's character frank the tank as portrayed by Will Ferrel

frank the tank 

A guy who always has one beer in each hands when he's clubbing. He always orders two beers at a time to save on tip. Frank the tank is likely to possess at all time a retarded haircut and don't know much about his life except that he has to fulfill his primary needs (i.e. sex, pizza, and shit/pee).

Reporter 1: All we know is that a guy with a retarded haircut and 2 beers in his hands came and started to yell at everyone for no reason.

Guy who's watching the news: OMG, hey dude ! frank the tank is on screen
