Similar to the "Dirty Aussie Beef Burger", the Dirty Aussie Double Beef Burger (D.A.D.B.B.) is male on male. It is the sex act of both men acquiring boners, tucking it between the legs and inserting it into each others asses while in the doggy-style position.
When you line up 2 cheeseburgers in a row, shove your dick in the middle, and proceed to fuck a bitch. Bonus points for having the chick being a fat hoe or having Aspergers.
Dude 1: yo bro, i just had sex with the kinkiest girl last night
Dude 2: damn bitch, what did you do Dude 1: She let me put it up her ass and pull off a double decker ass burger. I shoved my dick in the middle i and showed that slut a new world of pleasure.
Dude 2: kinky shit my dude. Now can you pull your finger out of my ass, it's beginning to hurt
