Sandy Turd Flex (STF)

When you're taking a dump and your butt flexes forcing the poop to retract into your butthole causing the sensation of sandpaper going up your butt.

first class flex

Military: when someone in your division is frustrated that you haven't been doing anything for the last couple of hours and wants to go home so your first class makes everyone stick around for hours doing something menial and totally unrelated

*Ship's power goes out*
E-3: LPO why are we even here? We're doing nothing, for a different division that doesn't need or want us, on a system that's not even ours, we've completed all our work for the day, and I just want to go home. Its 1500!!!
LPO: uhhhhhhh FIRST CLASS FLEX! Everyone stay behind for another two and a half hours to pick up trash on the pier!

first world flex

Also known as “rich people problems”, a “first world flex” is essentially a first world problem, but one that’s simultaneously boastful as well as whiny and arrogant.
