The act of ferociously rubbing ones butthole creating extreme friction. Sometimes causing the anus to become painfully charred.
Oh my God!! This old guy is blasecking himself in the middle of the street! I can see the smoke rising from his butthole.

Dude? Are you blasecking yourself in there?

If you mess up I am going to give you a real hard blasecking!
