The Manitoba Mad Cow is when you pick up a fat chick and while doing her doggy style, you squeeze and twist her titties like you'd milk a cow. Then you ram your dick in her ass without any lube, thus making her mad.
Ex: I hooked up some fat chick with a Manitoba Mad Cow last night, and it was awesome, she was so angry.
