A holy war declaired against anyone that disagrees with tween-aged girls or disses their crappy movie tastes, music, fashions, etc.
Teen girls are unbalanced, they go apeshit over little things. They will kill you for thinking the icons they've been told to love are lame. This hate is what causes them to wage a twihad against you.
Parents are common targets of twihad.
Tween girls launched a twihad against Sydney Dalton for tearing up Justin Bieber posters on youtube that included death threats.
