Slipping is NOT head movement?

[Youngblood]

Yea, it for me is basically a slight movement out of punchs target area, and throwing (usually inside) as a counter. That movement can be as simple as dropping down a few inches in stance.

The body movement in slipping is very similar to throwing punch without extending your arm. For example the motion of slipping to the outside to the jab would be like throwing a left-hook, and slipping inside would be like throwing a straight right.

You said that you usually slip toward the inside? I would think that it'd be to the more often to the outside since it'd be safer to (you wouldn't have to guard against their right hand).

Well, to sorta illustrate what I mean...often I will see say a left hook coming, and instead of moving away, I drop below the punch so it at best might graze off the top of my head...but by then a punch (s), usually straight right-left hook combo is being delivered.

So not moving in, but dropping down to set up counter and avoid punch.
