Right, so he was asking what he would call the two terms on the right hand side that add up to stagnation pressure. You only quoted the one term, and the term you quoted was the dynamic pressure term.
Missed an edit, my previous post is correct now. The point was that dynamic, impact, or stagnation pressure can refer to either compressible or incompressible flow.

Well, yes, and it is defined the same way in each case: the static pressure when the flow is isentropically brought to zero velocity. You just have to be careful how you measure it, as doing so with a Pitot probe introduces a shock into the flow, which is not isentropic, and you must incorporate the shock into the calculation. It is still fairly easy to do, though.
