tou·ché [ too·shay ]
In fencing, used as an acknowledgement of a 'hit', called out by the fencer who is hit. A referee can call out touché to refer to a touch being called – for example, the French call for "no point" is "pas touché" (English: not touched). From the infinitive verb toucher which means to touch.
Often used in popular culture and general conversation – for example, in an argument or debate. If one person presents an argument and another delivers a clever or appropriate response, the first person may respond with "touché" as a way of acknowledging said response.
