Mol is the first 3 letters in one of the dogs names (Molly), Luc is the first 3 letters in my cats name (Lucy) and Cass is the first 4 letters of the name of a rescued chow/akita mix puppy I found named (Cassie). She found a new home. I made this screen name like 2 yrs. ago though.

I like it, so even though I don't have Cassie anymore, I still use it.

Normally it looks like this: MoLuCass

It's pronounced like this: Mol_Lou_Cass.... errr, sorta..
