Soccer Ball and Boot Tie Clip

Why do soccer players do funny dances after kicking a goal? Do the players rehearse? Is there a post-soccer-goal choreographer? So many questions I just can't answer. Please note that the tie bar is silver coloured with a highly polished finish. These items are difficult to photograph and this one looks like a black bar, which is not the case. Dimensions (LxWxH): 71mm x 13mm x 7mm (approx.) Weight per cufflink: approx. 11.1g (heavy)
