Well, this is a funny one I think. The name of this combo was given by our videographer (Cedric Parlade) because everytime 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 arsenal' of moves.
