Bungee, for one, is a type of CORD that is made of elastic material and is used in activities such as bungee jumping. It is also used in other recreational activities such as rock climbing and rappelling. The elasticity of the CORD allows it to stretch and absorb shock, making it an ideal choice for these activities. The term 'bungee' is derived from the West Country dialect word 'BONG', which means 'to tie'.
