Baylife is a phrase people put at the end of forum and blog posts to show they are from San Francisco Bay but have moved to NYC and are open to beating the living shit out of you in game and irl. Bros only.
I saw Reginald put Baylife at the end of his LoL post hating on whatever the fuck he pleases because he is Reginald. We are going to throw down at the pier later. I am incredibly scared.
