"Philly", "Philly Cheese", or just plain "Cheesesteak". You can probably guess my first name from that. Apparently an ages old nickname for Philip is "Pip". Sister calls me that.
Phil is a great name to work up some nicknames with. I call my buddy Phil by the name of "Phil McRevice" - as in fill my crevice with a Utah slang. I also call him Philthy, P-Diddy, and Philthy Phil Philanthropist (after the great NOFX song).
