Queern't is a term used to describe anyone who isn't queer, whether they are an ally or not. It was inspired by the term cisn't. It is also an alternative term to cishet, as to prevent the term from getting over-complicated (cishetallo, monoallocishet) similar how queer is an alternative to LGBTQ+, as using queer can help reduce over-complication of the term.
