I'll tell you something I hate: when you buy some food product that claims to "naturally regulate your digestive system". Just drop the mealymouthed doubletalk and admit it already: "This product helps you take a shit."
I hate "Love conquers All"
So does Terry Gilliam...
I have always hated "What doesn't kill you makes you stronger."
(cue crappy-ass pop song)
I call BULLSHIT.
Of course it's bullshit - Nietzsche wrote it.
As an adult: YOLO (You Only Live Once) - Usually said right before someone does something stupid or dangerous or both.
And besides, everyone knows that you only live TWICE.
