When a male singer under the age of 18 sings about love and happiness and cute girls and living happily ever after hits 18, and starts to sing very sexual songs, cusses and has sex multiple times, usually after a very shocking/traumatic event that headlines the news for weeks.
1. Tammy(16yo): Oh my gosh I love Justin Bieber!!!!!!!!! He's so amazing, his lyrics are so thoughtful and nice!

Danny: Yeah they are now, but wait til he hits 18. He's gonna go through the Chris Brown Transition (The Crossover).

Tammy: ???

Danny: Yeah he's gonna make a sextape or something, get shunned, and come back with a rated R mixtape and from then on out he's gonna make songs about sex positions, smoking weed, and be in songs featuring lil wayne and busta rhymes.
