0 someone you love; a boyfriend or girlfriend:
[ as form of address ] Hey, bae. What's up?
But perhaps she was there to support her bae.
Others argue that bae is simply a shortened version of babe, which would similarly account for the rare ae juxtapostion.
And as more people say bae, it's likely that the meaning will shift in any case.
And bae was a buzzword that didn't have the weight or broadness they were looking for.
One day, bae is everywhere.
A good rule of thumb for now at least: if you would use the words boo or babe in some circumstance, you can probably use bae.
