Why was "tantrum" trending last week?
a winter sport using a guidable, single-track vehicle that has features of the bicycle, the bobsled, and skis. The longer rear ski is fixed, and the shorter front ski is mobile for steering; a saddle like that of a bicycle and a steering bar with handles complete the rig. The assembly is kept flexible to provide smooth passage over bumps and is lightweight, made of wood, aluminum, or plastic for portability. The skibob measures 1.9 to 2.29 metres (6.2 to 7.5 feet) in length. The rider wears short skis and a helmet, but goggles are optional
