When at an undefined age, between 12 and 16, an innocent, mild-tempered child turns into a crazy she/he-demon who seems to yell at everything because of various stupid reasons sometimes blaming themselves, or others. Extensive research is still being done into what hormonal imbalance is causing this.
E.g:
1: Hi Richard, what's wrong?
2: Nothin', my bloody daughter started going through teenopause today.
1:Ooo, that sucks man, good luck.

Example (in use)

1: Hay Jim, want to do something later?
2: OH MY GOD! WHY DO YOU HATE ME SO MUCH, YOU SHOULD GO KILL YOURSELF AND END YOUR SAD EXCUSE OF A LIFE!!!
