Bromine 

\BRO-meen\, noun. The essential binding element between the bro's in a bromance on a brolecular level. Few bros understand this however, as they rarely pass high school chemistry.

Under the right environment, such as in the presence of the catalyst 3OH3 (Oxygen Douchate), Bromine can form a durable chemical bond between two bromosexuals.
