You Aren't Clogging the Toilet
Toilet clogs are one of the worst things to deal with. Toilets are already icky just because nothing that goes in them is pleasant, but when they get backed up, we have to look our bodily functions straight in the face.
This is kind of sad since women have to use the bathroom just like men do, and it's not like it's unladylike to have to go or have a large bowel movement. It's blaming someone else over a trivial thing.
