The widely accepted theory held by many men that the female gender does not defecate or pass anything out of their anus. This theory is contrary to the theory that girls do, in fact, poop.
I wonder why is smells so bad after Beth came out of the bathroom, cause girls don't poop.

The idea that females do not "go number 2".

This is theory is usually sported my men who do not like the thought or fact of women using the toilet to put poo in it.

It helps certain people perceive women as more beautiful in certain situations.

This thought can also be modified to "Only ugly girls poo".
Judi: I gotta go poop.

Pat: Nope. Girls don't poop.

Judi: What?

The theory of Hot Chick Inverted Naval Vapor Intestinal Theory of Elimination

(HC INVITE)

Under the practice, beautiful women do not eliminate feces in the same manner as men. Rather, beautiful women possess a trait that is linked to beauty on chromosome 9. The trait grants beautiful women an inverted intestinal tract, such that the belly button (naval) of the beautiful women is the sole elimination medium, rather than the anus.

The waste matter passes through the inverted intestinal tract, where, as it approaches the naval, extremophilic enzymes target the waste and generate heat, thereby converting it from solid form to an invisible vapor. At the same time, additional enzymes act upon the transforming waste, such that it loses all scent.

The end result is that an invisible, odorless vapor is released through the naval and passes into the air around with absolutely no environmental or social consequences. This form of elimination is deemed most "noble", as it happens absolutely naturally and results in no disgusting expletives from men that otherwise would presume beautiful women poop.

On the other hand, unattractive females do not possess the linked gene on chromosome 9--as a result, they do not have inverted intestinal tracts, and such are forced to eliminate through the traditional "pooping" practice.
Random frat dude #1: Dude, that chick's so hot.

Random frat dude #2: I know bro, she definitely eliminates through HC INVITE!

Random frat dude #1: But girls don't poop!

Random frat dude #2: Dude, ya just don't understand.
