Magnum PI 

When you take such a huge dump it forms an island in the toilet. A Poop Island.

After last night’s chili dinner, I formed a Magnum PI this morning.

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.

Yo, last night I was banging your girl in her ass and she asked to look like Magnum P.I., so I helped her out.
