ex-squared 

Your first ex, in the event you've been divorced twice. This term avoids confusion, is succint, and has the added benefit of showing you have a sense of humor.

I'm on speaking terms with my ex, but if I never see my ex-squared for the rest of my life, it will be just fine.

Esquared 

To be Esquared is to pass the bar exam and be admitted to the bar in two States!

My bright and talented and awesome friend Amy just got her bar exam results from both Pennsylvania and New Jersey and passed both exams thus she is Esquared!
