dip: a dancemove excecutive, only to be done by slighlty bendy and physically "able" people, as demonstrated in the many "home-video shows" on television, can go wrong very easily, thus a little training and practice is important to do those moves correctly. Note! People in wheelchairs are very able to dance, although a dip takes practice and usually not funny.
"have you seen the dip for the crisps? no, i haven't, wanna dance?"
