A Comment On Transgenderism

[Foxboy]

"Resleeving" is essentially, like you said, swapping bodies like a set of clothes. It's best described (and where I got the term for the process) in the Catalyst Games RPG: Eclipse Phase:

We humans have a special way of pulling ourselves up
and kicking ourselves down at the same time. We’d
achieved more progress than ever before, at the cost
of wrecking our planet and destabilizing our own
governments. But things were starting to look up.
With exponentially accelerating technologies, we
reached out into the solar system, terraforming worlds
and seeding new life. We re-forged our bodies and
minds, casting off sickness and death. We achieved
immortality through the digitization of our minds,
resleeving from one biological or synthetic body to
the next at will. We uplifted animals and AIs to be our
equals. We acquired the means to build anything we
desired from the molecular level up, so that no one
need want again.

Bold emphasis mine.
''We don't just borrow words; on occasion, English has pursued other languages down alleyways to beat
them unconscious and rifle their pockets for new vocabulary.''
