Over recent years I've read so much about women being passed over, cut off, terms like "microaggressions", women getting less talking time in meetings, etc., that's it's made me extremely self conscious.
It's not even that I'm afraid of getting in any actual trouble if I say or do something wrong, it's just that I'm generally already somewhat anxious about how I behave around others and this has made me extremely aware of any time I might be too harsh, not really listen to someone, etc., that I've probably gotten overly sensitive.
This happens in the media a lot too (left and right). A single sentence (or even part of a sentence) can be plucked out of an interview, shown out of context and boom - the person seems like a monster. Someone might have best intentions, but not be very polished in expressing them. So why risk talking at all, unless we are 100% sure it cannot be misconstrued in any way? It is just easier to keep quiet. Which results in loss of lively, valuable discussions.
Some comedian (forgot who it was) mentioned that they don't like performing in colleges anymore as the audience is too sensitive. That is the situation we are in.
I've only heard it mentioned within gaming, and it typically means more than just bathroom (Encompassing instead a bunch of different biological necessities like bathroom, hydration, eating)
