Bromance is a portmanteau of the words bro or brother and romance. Editor Dave Carnie coined the term in the skateboard magazine Big Brother in the 1990s to refer specifically to the sort of relationships that develop between skaters who spend a great deal of time together.

Aristotle's classical description of friendship is often taken to be the prototype of the bromance. He wrote around 330 BC, "It is those who desire the good of their friends for the friends' sake that are most truly friends, because each loves the other for what he is, and not for any incidental quality." Numerous examples exist of famous intense male friendships throughout most of Western history.

A number of celebrities have engaged in bromances with fellow celebrities. Examples include Ben Affleck and Matt Damon, described as "perhaps the pioneering bromance in showbiz history."

Zachary Quinto and Chris Pine after the filming of the 2009 Star Trek film, have become a modern bromantic relationship, which has its own significance with regards to the characters they play on the film, i.e. Kirk and Spock, a legendary fictional bromantic relationship itself.
