One who is in to eating some serious ass! A tunnel rat is not a casual ass eater or one who may by accident come in contact with the anus while eating pussy. Tunnel Rat is reserved for those who have made an art form of eating ass!
After years of practice and honing my ass eating technique, I have finally earned the monacher of Tunnel Rat!!
A very very VERY lazy creature who sits at home all day and plays Assassins Creed Brotherhood. Little is known about this volatile creature, but it is known that they like to masturbait to 2 girls 1 cup.
That Tunnel Rat just got MRSA!
