means A single wide board you strap both feet onto sideways to slide down snowy slopes.

from Born in the late 1960s when American inventors started bolting two skis together or riding modified sled-like boards down hills — one early version, the 'Snurfer' (snow + surfer), was literally a kid's toy. The word itself is a plain mashup of 'snow' and 'surfboard,' since early riders and designers were chasing that stand-sideways surfing feel on frozen water instead of liquid.
