When a couple breaks up and the guy becomes needy on one of his bros.

When 1 Bro (or in some cases multiple Bros) embark upon a mission, or a journey--perhaps even a walkabout--wherein at the end of this outing there will be a second Bro (#2). Bro #2 may or may not have knowledge of Bro #1's quest; it is irrelevant. Also: does not necessarily have to be an epic odyssey; a pilgrimage of sorts. It can merely be a ten minute car ride for Bro #1 to your local Dunkin Donuts--where said Bro #2 works. Or, a bike ride across the street from Bro #1's house where said Bro #2 is in his garage with a blunt and a lighter; in waiting. Bro #2 does not have to be the sole purpose of Bro #1's travels--but, if there is a Bro #2 involved in the final stage of events--then that Bro #1 is indeed BROBOUND.

Little Timmy was indeed brobound; traversing the glacial fields, skipping over narwhals walruses and other Arctic life, he would do whatever necessary to get back to the S.S. Sea-ship and Captain Jimmy.

Brobound, Louis accelerated the Jeep to 90mph. For there was a massive rage/rave to be held in a newly constructed house, yet to be taken of the market. Louis new the best of ragers were held in the best of unsold properties, and this was indeed a "location location location". Louis also knew that his chums Chad and Bistro were hosting this jamboree--fueling his tenacious embers a non-quantifiable amount more.

J: "Dude, where is Peter?"
