Paper Minnows are the small fragments of toilet paper that remain near the bottom of the toilet bowl after taking a dump, wiping and flushing. Paper Minnows continue to float and move about the bowl in a fashion similar to Minnows in a lake, pond or fish tank and appear to be small opaque fish.
Dude someone just shat in there. Check out this toilet bowl. Look at all those Paper Minnows floating around down there. Whoa! Looks like one of the fish tanks in the pet department at Wal-Mart.
