gone rogue 

a state of defiance that ever so slowly creeps in after the tears and getting burned one time too many. when an abused person finally has their epiphany and realizes they are just everybody’s punching bag, a generally good person who always gives too much, loves too much, always first to apologize just rolls over and still everyone just keeps taking and using and asking for even more. when they’ve finally gotten mad and start tripping the system, misbehaving, being bad and breaking the rules for maybe the first time ever, they’ve gone rogue. funniest when it’s really out of character for someone and justified.

A great example is the Joker. Everyone gets it and actually roots for him even though he is bad, because they know what he came out of and he is finally fighting back. Going rogue against a corrupt system that always keeps you down is something people can get behind. It means going bad, turning to the dark side, going from a straight A student to someone who smokes pot and skips school.

boss: where is Amanda today? The meeting is in ten minutes and we need her slides for the presentation!
Amanda: -walks in very late with shades on snapping gum and with a Denny’s breakfast to go- I’ve got your damn slides and you’ll get them on USB at the meeting
co-worker: damn Amanda’s gone rogue!
secretary: did someone leave this photocopy of their ass in the printer on purpose because I’m offended.

gone like Roger Daltrey's shirt 

A way of emphasizing just how gone something is.
Typically used when something disappears with no trace of where it went whatsoever.

Derived from the Who's lead vocalist, Roger Daltrey, and how in the later years of the band, his shirt would just...poof. It's gone.

"Moooom, my tablet pen is gone!"
"No it's not."
"Yes it is! It's gone like...like...it's gone like Roger Daltrey's shirt!"
