tizaster 

When you're doing a girl up the butt, then you spit on her back so she thinks you're done (like a dirty Harry). She'll then turn around, and then you whip her right in the face with your shlong while screaming "TIZASTER, BITCH!" It's generally good to follow this with an angry dragon.

I was doing my girl like a bad mofo, and I slapped her in the face with my ten-incher. Knocked her out cold, and yelled "TIZASTER, BEUTCH!"
