According to Time Magazine, bae, pronounced just like the word bay, began as a term of endearment, usually applied to one’s boyfriend or girlfriend. It first turned up in rap songs around 2005.
It took on a wider meaning for anything generally good or cool. You can even say “This sandwich is so bae” or “My new Calvin Klein underwear is really bae,” and people of a certain generation will probably know what you mean.
The origin of bae, like that of all good slang words, is debatable. Some say it’s an acronym meaning “Before Anyone Else.” Another theory says it’s simply a shortened form of baby or babe, the latter which would account for the peculiar juxtaposition of a and e.
