out sarcasticize 

to defeat or to be defeated in a back and forth battle of sarcasm.

one may deliver a line of sarcasm, knowing it has a small chance of offending the receiver, at this point the receiver it may have offended delivers his or her own sarcasm back causing the deliverer to think they actually did offend the receiver. Really, the receiver was not offended at all but they have just now out sarcasticized this deliverer.
