A term referring to the sexually frustrated and socially incapable young males who all wear the same style of clothes, stalk the same females, and repeatedly talk in gay voices to eachother. It is generally very easy to spot a dude-bro, if you hear the word 'gay' or 'faggot' used in a derogatory way, look for a sideways hat or a Thirsty Thursday shirt(or collared shirt) and you will see a dude-bro.
Me: "Those guys just said Broken Social Scene is gay."
Fellow Intellectual: "But Broken Social Scene is the greatest band ever!"
Me: "Yeah, they must be dude-bros."
