dip snap 

A dip snap (also known as 'packing') is a gesture/hand motion achieved by loosely swinging one's hand quickly with the forefinger stuck out and the thumb and middle finger touching, causing the forefinger to strike the thumb or middle finger, resulting in a sound similar to the slap caused by a regular snap. It was originally devised as a way to pack the snuff, or dip, in its tin, done by simply doing the above with the tin held firmly in between the thumb and middle finger. It is often used by "dippers" as a sort of secret calling card, to announce to other "dippers" who know what he is doing that he is a fellow "dipper".

Tell Ricky to dip snap that can so we can get a pinch!
