when you and your fellow bro do something awesome together, and when both bros have a mutual feeling of likeness toward "The Tide" (Alabama Football)
Guy 1: My lacrosse team just won its 13th national championship!
Guy 2: Like Alabama University? Brotide to that!
Guy 1: Thanks for helping me eat all of these sandwiches my girl made. I think having you and all of my other friends over watching the game was the most chill thing i've done in a while.
Guy 2: Anytime, Brotide.
