1.
The overwhelming sense of not giving a crap about the horrendous amount of work and deadlines you have simply because it's Friday.
M1 - "Hey man, you wanna duck out early and go play some disc golf?"
M2 - "Don't you have a big report due on Monday?"
M1 - "Yeah, but I've got a case of the Friday Fuck-Its. I won't get anything done anyway."
