Not trying to be a downer, but what is the reason for your question?
What possible good would it do you to be able to cause a diarraha for a few days in a fight?
Your attacker beats you to death---then has to sit on the toilet a lot over the next few days--does not sound like a fair trade to me.

Honestly one of the things about PP is that they can be really "state dependent" in that hitting P2 on one guy will do "X" while on someone else--nothing, so I guess you could say that a given result is "true"--sometimes.
