Queern't is a term used to describe anyone who isn't LGBTQ+, 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.
