Vaguelabel describes when an individual uses a label, or multiple labels that don't quite fit their "true" gender, even though label(s) whose definition fits the individual's gender experience "better" are known by the individual. An example would be if someone identifies as a demiboy, even though the label libramasculine fits their experience better.
A vaguelabel individual can also use multiple labels that don't fit 100%, or they could have multiple "true" labels, but only use one "not-true" label. A vaguelabel individual could use these other labels for any reason.
