The combination of something being obscene and insane at the same time.
Obscene can represant the amount of money spent. "That's an obscene amount of money spent for the building of that hotel"
Insane can represant someone not of sound mind. "Hillary hit Josh in the kneecap, that's so insane."
Hiram- "Hey man, the amount of dough you gave that chick for her strip tease was way too much. She didn't even show her tits."
"Yeah, I know, it's so obsane. I should have asked for some nipple"
A conjunction of the words obscene and insane, used predominatly by my "inner circle" to describe situations and events that are simply too outrageous and/or ridiculous to be described by any existing word in Webster's Dictionary. It is a word reserved ONLY for extrenuating circumstance.
1.) Did you see what that bitch was wearing?! Holy crap! Feathers & sequins?! That is so obscane!
