Teengirlitis 

The plague of the 21st century, affecting 99% of the female population between ages 12-25. This disease is catagorized by the excessive use of the word "like", overreaction to trivial things such as boys, clothes, make up, explicit "love" stories, and terrible bands, artists, or groups in the music industry, such as the Jonas Brothers, Taylor Swift, Lil Wayne and more, and spontaneous meltdowns. There is no treatment for teengirlitis besides a good slap in the face or a kick in the ovaries. With time, the disease eventually devours itself and the sick returns to what is left of her rational mind, but the disease never truly goes away--it simply becomes dormant, waiting to strike at any given moment. Also associated with Fan Girl Syndrome (FGS)

Teenior Citizen

(noun)
A woman 50+ who still lives, laughs, dresses, dates, flirts, parties, or vibes like a teenager — but with adult money, adult confidence, and zero fucks left to give.

A teenior citizen is not old…
she’s vintage hot,
sipping cocktails, flirting with younger men, going to festivals, taking selfies, living her best life, and ignoring society’s idea of “acting her age.”

She’s basically a glamorous teenage girl trapped inside a fabulous grown woman’s body,
but with better taste, better boundaries, and better skincare.

Traits of a Teenior Citizen:
• shows up to brunch in crop tops at 53
• has better nightlife stamina than people in their 20s
• pulls younger men without trying
• lives like it’s senior year, not senior living
• gives “I’m too old for bullshit but too fun to retire from chaos” energy
• knows she’s THAT girl, and she’s right
• always glowing because she minds her business and moisturizes
• flirty, free, and fabulous
• the auntie everyone wants and every man fears

Basically:
She’s a cougar with teenage energy and grown-woman confidence.

3.
“She’s 52, but the way she flirts and parties? Total teenior citizen behavior.”
