When someone does something extremely stupid in a game or irl, you call them a brainlit. Can be used as a less vulgar substitution for dumbass.
Person 1: Oops, I didn't mean to!
Person 2: You could have easily avoided that you absolute brainlit!

A monumentally stupid person, retard, mongoloid, dingus, dumb shit, dip shit, shit for brains, ass hat, fuck head, knuckle fart, mouth breather, etc.
Wow, that brainlit had the nerve to question you? Fuck that guy!
