A twist of the phrase "grow up", referring to a person's incredible transformation. This is usually based on increase of style and self-confidence (and potentially one's squad).

When a female mentally tells her self that she is worth it, beautiful, and shouldn't care about what anyone else thinks. When she grinds on her own, she has a special look to her now that she accepts her self.
Girl 1: You seem different, in a good way.
Girl 2: Yeah, I had a glo up over the summer.

A glo up is when someone becomes confident, and believes in themselves, and they don't give a fuck about what anyone says about them. That's what makes them seem more beautiful.
S/he had a glo up because they believe in themselves and has become more attractive.
