look up any word, like turnt:
the attitude one has on any given friday in which they dont care about anything that happens
DeShwan: Aren't you going to work today?
Mike: Naw man, it's Fuck it Friday
by Danielle's boo June 08, 2009
The last given Friday of each month, in which no fucks will be given.
1. "Should I change the baby? Hell No, It's Fuck It Friday."

2. "Dude wanna get some hookers and tear it up tonight?" "hmmm.... Fuck it, It's Fuck It Friday, let's do it!"
