Nothing. A male will do this as a sign of strength and domination in front of other males. They will generally make a "machine gun" type of low pitched, rapid fire grunting either before, after or during such a hip swaying display. If your male pigs begin to fight after a display like this (a rare event) then you may want to separate them, but simply swaying and "machine gunning" is not anything to be worried about. Males can be kept together in large cages if raised together as juveniles. I would not recommend multiple males housed together in general, but if raised together, this can work. Good luck with your guinea pigs.
soak it gently with mild soap and a cloth wash carefully.
Laugh at him, or pick it off. Just make sure to wash your hands afterwords. But seriously, no major concern.
He has wet tail! Get to the vet fast! :(

smell of poo
no, all your poo would get stuck inside of you and then you would die
if you want to create a smell like dog poo then soak a banana in lizard urine.
