dirty boston

when having sex, you pull out of the dog, cum in its bowl and mix in some kibble. Mix it with your dick and share it with your dog...while singing "when the saints go marching in"

Come here puppy, i made you a dirty boston!

Dirty Boston

When your girlfriend throws all your shit in the street so you fuck her in the ass wicked hard and then slap her in the face with your shit stained dick.

Did ya hear? Mickey and Rhonda's split up after they had a Dirty Boston last night!
