The title an asshole CEO (generally a sole founder) puts on their Linkedin title to show they have the ability to fire anybody.
Random dude: Where do you work?
Albert: I am at the greatest game company around called BigVikingGames
Random dude: Cool, what do you do there?
Albert: I am the janitor, I just take out the trash!
Random dude: cool story bro
Sometimes startup founders or executives will use this as their title to appear humble but it ends up being super obnoxious.
Matthew: why are you listed as janitor on LinkedIn aren't you the CEO?
Kilim: Oh I just wanted people to ask me about it so I can tell them my real position.
