Ostalgie

(n.) (Ger) (also 'Ostalgia')

Nostalgia for life in former East Germany; portmanteau of Ost (east) and Nostalgie (nostalgia)

Also applicable to nostalgia for former socialist life in other Eastern European nations.

Arguably more common than 'Yugo-nostalgia'

The life recreated in Good Bye Lenin! is, in part, representative of Ostalgie.

Ostanik lean

The Ostanik lean was originally created at north Marion high school after a f-150 5.4 triton v8 revived a deafening exhaust and a lean at the point that the hitch almost touches the ground. The it revived 28 inch “dubs” and then factory wheels. This vehicle sounds like a raspy gramma coughing but moves like a sloth!

Holy shit that ostanik lean is disgusting

OSCtard 

Someone in the OSC, usually a little kid, who is extremely impatient and toxic. They can't accept criticism and whine over every little thing they don't like, such as an episode of their favorite object show not being released. A lot of them also steal other people's content, sometimes for their own profit.
Could also refer to someone who has a bad reputation in the OSC for things such as content theft, sexual harassment, bullying, etc.

Basically, an absolute idiot everyone should stay away from.

"For not releasing bfb 13 in 3 months, I am unsubscribing you and reporting your latest video"

"Okay OSCtard"
