Mostly used in reference with anime characters of typically traditional feminine traits, specifically wearing the clothing apparel known as skirts. This term implies that no one knows what is under the skirt and whatever is under the skirt is the observer's choice, implying the aforementioned anime character might be a femboy or an actual girl, or perhaps an all devouring eldritch being. This term was arguably first used by semi-popular American/Serbian YouTuber LivingIronicallyInEurope, in reference to his YouTube account's PFP.
John: Man, hentai's so confusing nowadays, you never know who's a girl and who's a boy.
Rohn: I know, everyone's wearing a Schrödinger's skirt.
Guy 1- The girl says she's a pit bull in a skirt, but she kind of looks like a poodle to me.
Guy 2-I know you're thinking that she is funny looking, but don't underestimate what she will do to prove she is not one of the poodles! She thinks you're disrespectful and wants to fight you now for thinking she looks like a poodle in a skirt.
A skort is a comfortable skirt of any length with a pair of shorts or trousers underneath it. The shorts or trousers are fixed to the inside of the skirt, so it's like you're just putting on a pair of pants but it looks like your wearing a skirt.
Notes:
- Skorts are usually bought by young girls because their mothers whon't let them wear minis
- Skorts are terminally ugly - They get hot and uncomfortable in warmer weather because of the double layer.
- They are uncomfortable to move in if they are long, because you can't move your legs very well and it gets sweltering. There is a tendancy the chafe under these conditions.
