Shma

Shma (SHH-MAH): You have to say it in a sad & angry is a name you can call your ex boyfriend/girlfriend.. You just don't even want to say their name any more so you can name the ex a Shma...

An ex that has left you and you have some bitterness towards them.

Almost like a Shmuck but he's not even worthy enough for the whole word..

"I seen Shma at the mall"
"Shma with anyone new yet?"
"Can we please not talk about Shma anymore"
