What is Teen Granny?
A Hot looking chick in VERY sexy clothes. Then you see her face and she's in her 50's or 60's trying to look young and sexy.
BOB:"I saw this really hot looking chick walking in front of me at the mall today"
Hank:"Oh yeah, did you talk to her"
Bob: No once I got close to her and she turned around I saw she was like 60, she was just being a "teen granny", it was gross!
