Raider Blastmaster

When you pop a thumb up a girls asshole while sticking two or more other fingers in her vagina.

Mikey: "Yeah bro, I was with this boning chick last night and I totally gave her a good old raider blastmaster. It was pretty sick."
Jim: "Dude noice"

blastmaster

Demolition man or bomber.

Twisting the strangle grip
Won't give no mercy
Feeling those tendons rip
Torn up and mean
Blastmaster racks the ground
Bent on survival
Full throttle hammers down
A deadly scream

All Guns, All Guns Blazing!

(Judas Priest - All Guns Blazing)
