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.
