the space at the center of the bellybutton.

if there's funk inside of he bellybutton, the cleo can be difficult to spot. that situation is called a missy-cleo.

the cleo smells kind of funky but can be used for many pleasurable things if you read between the lines.
guy- hey, wanna see my cleo?

girl- ew no
