Usually a white male between 30 and 40 years of age. Wears affliction clothing and lots of axe. Not typically as much of a douche bag as "bros" but still tries to act the "tough guy" role. Usually married with kids, the old bro, tries to cling to youth by dressing and working out with real bros. Can be spotted by their lack of matching clothing, and they are usually injured because they try to keep up with young bros at the gym.
Dude, that old bro busted his knee trying to squat too much. But he does have a pretty rockin affliction shirt on.

Get the Old Bro mug.
When one of your best buddies decides to ditch you and your friends for this new girl whom he just met, but can't seem to ever leave her or even want to.
"Hey man I haven't heard from you in a while. Why don't we get the crew together and hit the bar tonight?"
--"IDK dude I just met this girl a few days ago and she's perfect, I can't find one fault about her!"

"Well keep looking! If you let her know how you feel this soon she will control you and you'll be whipped."
--"Nah not this one, she is different, we are equals in this relationship and she is my dream girl!"

"Ah sounds to me like your choosing new hoes before old bros! Have fun with that!"
