A natural feeling experienced by beta men when they know that they are dating a female that has been much more promiscuous than them. It often leads to break ups when the beta male can't deal with his girlfriend's past and loses the desire to commit to her.
The feeling of being a teenage girl always made fun of, never enough, jealous of even your best friends, not pretty and not smart. Characterized by depressed feelings and then waves of maniacal tendencies to please everyone. Largely not accepted as a construct solely for growing girls, as their emotions are purely assumed to stem from their menstrual cycle.
A: "Why does Betty act this way? She must be on her period!"
B: "No you dumbass! It's simply the patriarchal system that undermines girls from a young age that makes her feel this teen girlangst."
A term used to describe idiot teens going through puberty who think they're depressed when it's actually just their hormones taking control of their brains. Eventually they either get over it, dwell on it the rest of their life, commit suicide, or a combination of those three.

Teen angst is my friend. A social life is not. </3
