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)
