Why you in my phisical

A phrase said when two people are in an altercation and one of the two moves uncomfortably close to the other, and causes the other to shout, "Why you in my phisical?".

Douche: You hittin' on my girl, bro!?
Nerd: Dude, why you getting so close? Why you in my phisical? Get outta my phisical! I said get the fuck out of my shisical, motherfucker!!!
