Facebook exercibitionist - A person who yells about their workout on Facebook like they

A person who yells about their workout on Facebook like they're in the NFL, even though their gym is a couch and their weights are their phone.

I did 10 minutes of workout. I’m gonna be a pro. 🏈

I did 5 sit-ups. My phone fell over. #SitUpPro

I did 3 push-ups. My couch laughed at me. #CouchGym
