portmantbro 

A portmanteau is where two or more words are combined to make a new word (e.g. bootylicious, turducken).

A portmantbro is a portmanteau where one of combined words is "bro" (e.g. brogrammer, broga, humphrey brogart, broadkill, etc).

Me: I tried going to broga for the first time yesterday, turns out it was a bunch of brogrammers. I was totally broadkill.

Grandma: Can you go a single sentence without using a portmantbro?

Me: Chillax Humphrey Brogart.

prom bitch 

A prom queen (or king) candidate that is obnoxious, self-centered and is practically foaming at the mouth to be crowned. A promzilla. Also, PROM BITCH is the original title of author Ami Allen-Vath's YA novel, LIARS and LOSERS LIKE US.

Can't believe she's nominated for prom queen...more like prom bitch.
Not to be a prom bitch but she didn't even match her cummerbun to my corsage.

ProgMo 

A term used primarily on Twitter to refer to progressive members of The Church of Jesus Christ of Latter-Day Saints (Mormons). ProgMos believe the church should change its stances on issues like gay marriage and abortion to reflect modern views. ProgMos are typically socially liberal and often openly critical of church leadership.

ProgMos think the LDS church will someday allow gay temple weddings.

He doesn't like President Oaks so he is definitely a ProgMo.
