frisson [friˈsõʊ; Fr. friˈsɔ] n.
1.) A moment of intense excitement; a shudder (American Heritage Dictionary of the English Language).
Etymology: French, from Old French fricons, pl. of fricon, a trembling, from Vulgar Latin frictio, friction-, from Latin frigare, to be cold.
"Most English-speakers are aware that the Frenchindefatigable trend-spottershave picked up words such as le weekend, un snack and le club; and as a result of this quest for novelty French is rife with anglicisms. The French feel the same frisson from saying le smoking (meaning a tux) that English speakers feel from saying frisson" (The Pillars of Hercules, Paul Theroux, 1995).
I know, another French word. But I heard this one the other day (Rob Brydon said it on "Would I Lie to You", actually) and I've never quite been sure what it meant, so I wanted to sort it out.
