Uses an “invisible dice only they can see” that somehow keeps rolling nat 20s

Keeps cancelling last minutes for “another, cooler campaign with a hotter GM”

If another player has the spotlight, they scream until it’s their turn

Their “character sheet” is just a laminated card saying “fuck you”

Every time you introduce an NPC, they introduce a bigger NPC who beats yours up.

Savescums. You’re not sure how either, to be honest, but its very annoying.

No only minmaxes, minmaxes in a different system to the one you’re playing

When asked if they’ve played before, they chuckle darkly and refuse to elaborate

Their in-character goal is “be in a campaign not run by a moron”

If they don’t like a GM’s ruling, they just fucking kill them
