cis by default

Cisgender by default. This concept originated from a blog post made by an user going by the name of Ozymandias.

Taken from the aforementioned blog post,

"I think you could probably tell them apart by asking them the old “what would you do if you suddenly woke up as a cis woman/cis man?” If they instantly understand why you’d need to transition in that circumstance, they’re regular old cis; if they are like “I’d probably be fine with it actually,” they might be cis by default."

Essentially, a cis person who does not feel a very strong connection to their gender, and only identifies as such by default.
