To me, it's just another example of MP not controlling himself, and sticking his foot in his mouth.
It doesn't matter HOW he meant it. The fact he said it, even under the guise he was off-air, speaks volumes. Enough already. Grow the F up. Sure, depending on context you could take it as a joke (all those nutty sharp high notes, har har, etc.). But MP just never seems to get the big picture. It's sad, really.
