Define Magnum Pi Meaning

Magnum PI's
Very tight, upper-thigh length shorts that were popular in the 1980's and were a staple of Tom Selleck's wardrobe in the popular television series Magnum P.I. These shorts usually clearly outline one's package and leave nothing to the imagination. Frequently worn by those with a mullet.

I was out of clean clothes so I threw on some Magnum PI's. I spent all day tucking back the meat to keep from playin turtle and scaring the locals.
