P-Shift means Physical Shifting . In other words, transforming and stuff. No, it doesn't work Kenrajy. I believe that is all fake.
This is from the Therian Wikia :
"A physical shift (or a P-shift, for short) is a physical change into another form. Of all the shifts, this is the the hardest and takes a lot of dedication, time and practice."
Hope I helped!
Blessed Be! )O(
