Smartbell

Smartbell: noun. Weights generally used for arm exercises and other gym activities. Unlike their more common cousins, dumbbells, smartbells are wider in the middle and thinner on the ends. This means a more even distribution of weight, a difficulty of grasp, as well as higher entropy and inability to hold the object. Smartbells have caused more accidents in gyms and sporting centres than tennis rackets and toilets combined, which is impressive indeed. It is virtually impossible to hold a smartbell for longer than 10 minutes without it slipping out of the hand of the holder.
