Tunnel Rat 

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!!
