Filthy Friday 

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.

Filthy Frida

A sexual move similar to the famed Dirty Sanchez Junior but in this case, the finger that was inserted into the anus is drawn across the brows to create a unibrow rather than a moustache. Commonly used by butch lesbians in New Zealand, it is named after famed non-plucking bisexual artist Frida Kahlo.

Poor Jenny had no idea that Rhonda had slipped a Filthy Frida on her, until she walked out of the bedroom into the party again . . .
