Generally a vehicle or a vessel of some sort that attracts other males, platonically, to each other. Often this will be a large truck, sports or muscle car.

The state in which a Bro can be found lounging, relaxing, "chilling", most often with fellow Bros. The attire is crucial to the success of the Bros "lounging". The Bro will often be wearing their Adidas flip flops (the ones with a single velcro strap across the toes), tube socks, ill-fitting basketball shorts, and most importantly, a cut-off tank-top which is either a ridiculously motivating Nike slogan, or their 2006 Wrestling championship. The Bro will often open their door eating a Jimmy John's sandwich, with a Natty Ice to nurse the hangover from their Bitty infested evening last night. In the background you will hear either football or Call of Duty.

Bro to Bro is the deepest commitment/ the deepest promise you can make, this cannot be broken. you can ask someone to say "Bro to Bro" or say something "Bro to Bro", stronger then saying "on god" or any other ones. If someone you know says something on Bro to Bro it is to be instantly accepted, without a doubt, until proven wrong. SHOULD IN NO WAY BE OVERUSED FOR DUMB THINGS
