A combination of the words "trans" (as in -gender or -sexual) and "paralysis".

This is when a trans person attempts to do something associated with their acquired gender, but then getting scared and not doing it.

Examples include using the "correct" bathroom/toilets or dressing in a particular way in public.
Person: How come you just went in the mens'?
Transgirl: Just a bad case of transalysis.
