JEM jem : (COUNTABLE NOUN) a subjectively exceptionally wonderful experience that is currently available to be had.
The top bar at the Brass Bell in Kalk Bay is a total jem. It is without a doubt the most authentic pub experience in the world.
Someone who's ugly but have a beautiful and kind girlfriend.
Jem is hungry and wants plokplok always.
A cunt who is perfectly imperfect, doesn't pay you back for a long time.
Jackson is such a jems he didn't pay me back the 2 dollars i lent him a month ago
