Filthy Beyblade 

like a Mexican Lawnmower, but the anal beads are in the dick. The goal is to pull the beads hard and fast enough to rip of the entire dick and have it spin on the floor, just like a beyblade. Unlike a Mexican Lawnmower, this process requires no waiting to complete.

My Homie wanted some CBT, so I recommended the Filthy Beyblade since he liked beyblade as a kid

Filthy Uncle Fester 

Combo Backfire Blumpkin and Dirty Sanchez.

Whilst receiving a good and proper skullie, it occurred to me that this was a fine time to introduce her to my "Filthy Uncle Fester". I gave her the old reach-around and pulled a fine example of last Tuesday's meal from her behind whereby I tactfully smeared it across her upper lip while my exploding fecal deposit caused roiling, brown toilet water to splash upon her chin.

filthy filth 

Filthy filth is filth so filthy you want to blind yourself.

When Trevor found Scott's cache of "Pedophile And Shaved Goat Magazine", he screamed "Filthy filth!", and tried to gouge his eyes out.
