The superslick design of the new smartphone makes it very appealing to customers.
Superslick is formed from "super-" (meaning above or beyond) and "slick" (from Old Norse *slykr*, meaning smooth or slippery). The word describes something that is extremely smooth or slippery, going beyond the usual level of slickness.
Think of something that is 'above' ('super-') being 'smooth' ('slick') — that's why superslick means extremely smooth or slippery.
