depends on the character for me and the circumstance for me tbh. modern day characters are less likely to get me to question it, but fantasy characters would weird me out admittedly.

like if disney rapunzel just suddenly swore in every other tag i would definitely think that's terribly ooc, but if she's been hanging around someone who swears a lot then yelled FUCK one day then got all omg i said it and had an existential crisis for 6 tags i would find it funny.
