Poop size and consistency is another one of the tools the patriarchy uses to divide us on an arbitrary basis that reinforces the gender hierarchies disseminated within society. The stereotype of solid, large poop as "manly" further contributes to sexist notions about the intersection of gender and areas such as health and diet.
Consequently, due to its high fibre content, eating Weetabix is seen as an intimidating sign of strength and ability to fight in masculine-normative spaces (as evidenced by this advertisement).
Therefore, the niche meme of associating Weetabix with forced feminisation (as a result of the book series Sisters of Dorley Hall) is more radical than has previously have been hypothesised.
It's a way of claiming high-fibre diets as a possible component of femininity, further undermining the insidious ways in which the patriarchy exerts pressure to restrict people's options so as to force them to conform to imposed standards of binary gender norms.
