blister fister 

Taking a lit cigarette and burning the rim of the anus. As the blisters appear you pop them with a forward motion of the fist using the pus as lubricant for easy insertion.

My butt is so sore after a blister fister

The act of inserting ones fist into a womans vagina while twisting it rapidly.

Man 2" Yeah bro, I gave her the fisterblaster last night"
