What's it then? Is it a freakin wet pad? Look, I'm not trying to discredit St. Pierre's victory but rather questioning the legitimacy of the action.
At no point in that gif does St.Pierre's cornerman touch him with vaseline. His left hand has nothing in it, the other hand with the jar grazes GSP's shoulder. As has been previously explained, fighters get Vaseline put on their faces in between rounds to minimize the possibility of a cut. At that point, GSP's just finished a round, and his people are likely trying to get him to his corner; not as you seem to be implying, greasing him up in front of the cameras
