Well, this is a funny one I think. The name of this combo was given by our video grapher (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 dance arsenal of moves.
i was reminiscing my Salsa dance in Manila when i watched your video,,i miss this sultry salsa i live here in Bishop, Ca. i am introducing this Salsa in this town ,,actually this place is country style.
