squick

An interjection expressing physical disgust at an object, action, or situation. Somewhat similar to ick, but implies more disgust than simple distaste -- something that elicits the gag reflex would also be worthy of a "Squick!" For example, if presented with a plate full of broccoli for dinner, one might say, "Ick." One would say "Squick!" if this broccoli had been at the back of the refridgerator for two months and was now moldy, slimy, and rotting.
