Unprofesh

Because one must never be caught by surprise. What if your ex-best friend shows up and emotionally wrecks you for the rest of the night? Or that cute guy from work you've been crushing on but trying really hard not to make out with because that would be totally unprofesh?

If you're not a millennial — and even if you are — you might think totesing is atrosh and unprofesh. But get used to it. Though no one is quite sure where it came from, this way of speaking has been around for well over a decade.

Any action that makes an umpire look foolish, or casual, or dorky, or in any way less than 100 percent serene, is considered highly unprofesh.

Because regardless of how you feel about them, someone at your job definitely thinks they're unprofesh—and that someone may be the very same someone you need to impress on the day you decide "these Lulus are totally fine with a blazer."
