A dougie is a huge mistake, a piece of shit, or a thing that sucks massively.*
*Inspired by the shitty song Teach Me How To Dougie, which has an overly simple beat and is done by a group called Cali Swag District who sounds high as proverbial shit. They should be called High as Balls No-Swag District.
Furthermore, Teach Me How To Jerk by Audio Push is legit.
Lola: "Oooh, girl, I went to get my nails did and the bitch messed dem up and now my nails look like some fuckin' dougies."
MoReen: "Damn, that is some dougie shit!"
