Forever 13 

Hot Topic. Used as a mildly derogatory term and a wake up call towards grown men and women who are stuck in the early adolescent frame of mind.

"Seriously Paul, you do realize you're 32. So why don't you just quit wasting your hard earned money in the Forever 13 and come with me to Marshalls?"

forever10 

the kind of friends who never want to be apart. all it took was a couple of days for them to become inseparable. they're the kind of friends who would sit in the hospital with you for 5 hours like your mom. the kind of friends who judge you for making bad life decisions, but make them with you anyway. they're best friends, and always willl be.

foreeeeer10, i wanna be forever10.
