What two bros in a bromance call eachother. Not to be confused with a homosexual relationship, using this term signifies a strong friendship between two completely straight males. Significant brothers have love for eachother but are not in love with eachother.
Girl: Are you gay?
Bro: Nah, I just have a significant brother.
Some Kid: Do you know Sean?
Some Bro: Know him? Bro, He's my significant brother!
Bro: Nah, I just have a significant brother.
Some Kid: Do you know Sean?
Some Bro: Know him? Bro, He's my significant brother!

Get the Significant Brothermug. Pam: did you hear Brittany got married? I wonder who the groom is...
Karen: oh, she married her step brother. Such a good love story, when one finds romance with their significant brother.
(Cue banjos)
