A phase that a nerdy, innocent, or shy girl will go through in highschool or college where they suddenly become more attractive through puberty, knowing how to apply makeup, learning how to dress, or present themselves better, and subsequently attract the attention of many previously uninterested guys.

Girls who enter metamorehoes-sis tend to fall victim to enjoying the newfound attention, and will play with all of the guys without getting with any of them. The word for this type of girl is called a Tugger.

Metamorehoes-sis girls will oftentimes embrace their shy innocent personality, and while they might not be aware of or intentionally be leading so many guys on, other girls will definitely be gossiping about how they put up an 'innocent front' while wanting the male attention. Whether this is true varies on a case by case basis.
"Yo, Ashley is hot now."
"Yup. She entered Metamorehoes-sis. She asked me to wait for the bus with her lol. No way I'm falling for that."
"Good for you man, apparently Jonathan has been carrying her bags for her recently."
