My Life is Bro

Used to describe events that are especially brotastic.
Today I chilled out by the pool with my bro, drank some beer with my bro, and got high with my bro. We're just two bromosexuals in a bromance. MLIB

The hardest decision I had to make today was deciding which set of sperrys goes best with which one of my many lax pennies. MLIB

Today I had a Dave Matthews jam sesh, watched some lax, fucked my girlfriend, and downed like 16 natty ices. I did one of them more than once. Let’s just say it didn’t involve sports, beer, or music. MLIB.
