The act of plopping a solid turd on ones feet then slapping their genitalia back and forth with their left hand. After smear the little brown eye escapee onto the back of the victims eyes while using your tounge to harden the nips of the victim.

Filthy faggot is a euphemism for a lurid and flaming stick, thus can actually refer to a flaming log or a cigarette, as in Jack London, for example. In the more modern world, such a perjorative term is directed at those who are close relatives of that wicked species of mankind known as the "fudge packer." These vile creeps like to pump the piles and pound the stick in rancid gut gravy, or crack paste, as if they were on a ride at Disneyland. These are exceedingly lurid people, possibly possessed by wicked fag devils, and they are one and all totally sick'd out of their blooming fruits!

Cousin to the famed Dirty Sanchez, this excrement mustache is composed of diarrhea for a fashionable, modern look. Having liquid properties, the mustache tends to flow around the edges of the lips, the leaks creating a nice handlebar stache.

Not showering on Friday morning (or Thursday night) due to laziness brought on by excessive alcohol consumption. Such an action leaves one smelling less-than-perfect all day long on Friday, necessitating an all-too-brief wash-down after work or school before the nightly cycle of drinking begins anew.
I was going to meet Becky right after work, but I had some Filthy Friday action going on, and didn't want to meet her wearing the same outfit as last night.

Similar to the Filthy Sanchez, but instead of giving her a moustache across her upper lip, you smear your finger across her teeth and gums

A sex act. When you’re making sweet love to your lovers bung-hole from behind. Then you pull it out mid-coitus with their brown love juices on your grease missile. At this point take those chocolatey pastels and paint a Wilson face onto a volleyball like in the Tom Hanks movie. As you resume the hedonistic act and at the exact moment of climax, spike the volleyball onto your lovers back and cry out “Willllllsoooooon!” leaving a muddy facial imprint on their back.
