Well, this is a funny one I think. The name of this combo was given by our video grapher because every time I taught the combo I would make a "boop" sound similar to that one on the radars in submarines. If you would like to do the "boop" sound, it is done on the counts of 1 and 5. I usually use this combo to give me more time to think what move/combo I will be doing next - so basically I use it to stall. ;-) Good to have it in the salsa dance arsenal of moves.
