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).
Noamee: "Remember that kid nerdy kid Loganus from High School?"
Mayana: "Yeah but have you seen him now?!?! GLO-UP!!!!"
Noamee: "I wish a nigga would"

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.

This is what cats do when they claw into you whilst you are petting them.
The cat commenced it's, most annoying, glouping of my leg; whilst I was petting it.
