a spare pair of hands located around your chest area. these are useful for eating popcorn in a cinema and texting while driving. unfortunately these are currently medically unavailable and must be provided by a friend standing directly behind you with their hands under your armpits. can be good fun to run behind people scream chest hands and attempt to insert your hands under their armpits without permission.
