A slightly derogatory slang term for most “millennials” who have huge egos and think they know everything but don’t display much intellect, so when they start taking you can tell they’re really full of bullshit.
My friend Sorren was born in 1994 and is adamant that Peru is the capital of Brazil! He’s such a frustrating Bullennial! He can’t even admit he’s wrong when we look it up on Google and show him!
