When you talk too damn much, offering up self congratulatory stories for no reason. When a guy runs away with a conversation and uses every opportunity to big himself up(i.e. to make oneself look better)To embellish.

Get the Bomug. A fucking loser with a giant truck who hangs out at either the tractor supply or local wal-mart after the hours of 9pm. A BO may have one or more giant antennas the size of a basketball hoop COMING OUT OF THEIR HOOD built for landing spaceships or attracting other BO'S or mudbumpers. It is not uncommon for a BO to use words like < fixin, yonder, thurr, >
