ass-tanking is when you put your index finger in your crack, just like you do at the gas station with gasoline gun. then, you keep it there until the finger is "ripe" and ready. after you smell it. the longer you tank, the more enjoyable it is.

Tank Top Al is a gamer. He will excrete noises such as loud screaming. He is a man among boys, the only true chad you'll ever meet. He wears only a singlet and running shorts and boy does he rock it. His muscles are incomparable. To date a Tank Top Al is to date a hurricane of testosterone. He may be gay but he doesn't care. Speaking from experience.
Similar to a Metro tank transfer, however one seemingly straight male is unable to exchange fluids with another seemingly straight male due to gis testicles being removed.
