1) The act of mentally shifting a hyphen in a sentence or comment which contains the pattern {adjective-ass noun} Used for personal amusement only. From the webcomic xkcd (www.xkcd.com/37)

2) Verbally expressing this mental re-hyphening to show discontent or apathy toward a person's vocabulary, word choice, comment, or the person in general.

Take note: Not all hyphens can be shifted for this effect - i.e. phrases like No-Talent Ass Clown or Punk-Ass Bitch - because the hyphens either don't make sense anywhere else, or they're just funnier where they are.

2)
Person One: I had a nasty-ass cold last week.
Person Two: An ass-cold? Is that some new STD?

Person One: Goddamn, I'm one bad-ass fucker!
Person Two: Yes, I bet you're a horrible ass-fucker, and I'm sure your boyfriend would agree.
Person One: Quit re-hyphening me, you ass bastard!
