means A liquid cleanser formulated to be used with water in the shower, typically lathering with synthetic detergents rather than true soap.

from A straightforward compound of 'shower' (from Old English 'scur,' a brief fall of rain or hail) and 'gel' (from Latin 'gelare,' to freeze or congeal — the same root as 'gelatin'). Liquid body washes emerged in the 20th century as chemists learned to make synthetic surfactants that could be thickened into a gel, letting marketers sell something that felt distinct from a bar of soap even though it does much the same job.
