Double Barrel Fun-Time 

A new and innovative sexual position between two homosexual males. The male with the smaller genitalia will insert his penis (or barrel) into the other gay's penis, thereby arousing and pleasuring both partners.

"Let's get you home so we can have some crazy double barrel fun-time"

Gayboy#1: "I can't wait to shove my tiny pecker inside your huge willy"
Gayboy#2: "Double Barrel Funtime is super sexy fun, even for the person getting his boner penetrated!"
