Branden Grimm 

Someone who drinks a lot of beer and is always a good time when he’s drunk! Can find them at any house party or bonfire drinking Busch light by the case. Also had a slightly above average pecker but will always leave you wanting more and wondering about what could have been. Also could find him with a Brandon Harris or a Tyler Reid.

Her #1: A Branden Grimm tore my ass up last night

Her #2 : What all happened?

Her #1: He tore my ass up for 45 seconds and passed out because he drank a case of Busch light!

Her #2: Damn girl me too! At least it was slightly average!

Her#1: Yeah it was pretty good to be honest!
