The Fucking MAN!
Optimus Prime burned down an orphanage while eating beef jerky and cutting down the rain forrests. Then some femminists came up to him and started their bitching, so he starting punting them across the yard. Then he went to a feminists meeting and started shooting them with lazers that came out of his eyes and making then run back to their men for protection since women are weak. Then his gf started bitching him so he slapper her upside the head and she cooked him some dinner.
