JGN 

Short for "Janky & Gaudy Nemesis." Describes someone who you despise because they are so tasteless, ostentatious, fucked up, and in their own bubble because they refuse to accept reality.

"I don't know what the hell she is thinking but dayam, she's a TOTAL JGN and no wonder no one likes her!"
