Er, no you didn’t. If “womansplaining” also commonly described a condescending attitude towards others I might have used that instead. My earliest memories are of being shamed for playing with dolls and I got called “tranny” all through secondary school. I don’t reinforce arbitrary gender boundaries through language. If men can use words like “bitch” or “fish” to describe themselves a woman can mansplain. But 10 out of 10 for effort.
