Verb, derived from pork, means "to get up on" or fuck. Refers to a rebel fighter, Red 6 (Jek Porkins) in the original Star Wars. His final words "I'm alright" as he is getting blown up perfectly capture the willingness to put yourself in harms way to get a piece of that ass. Also, his physiology is that of swine, which reinforces his name and this fine word we are defining now.
Oooohhh, sweetback! I'd be spacin' gs if I could porkinz up on the fine biznitch.
