Naco
A meme term for the tank Necromancer in diep. io, but it's also used to insult people who think they're cool just because they know how to say 'chingón'.
'He's a naco, he plays diep. io and thinks he's a pro.'
'That guy is a naco, he uses the Necromancer tank like it's a superpower.'
'She's a naco, she says 'chingón' every time she wins.'
