there is, it’s a NOTP. you don’t like the ship, maybe you even hate it, but you don’t pass judgement or harass people over it.
The word for “this ship bothers me because reasons” is ‘squick” btw
squick can apply to many things besides a ship, too. a squick is not a trigger, because it doesn’t cause panic attacks or bring up memories of trauma or anything, it just really really grosses you out. you might have a reason, you might not, but a squick is something you just don’t ever wanna see, but like NOTP, it doesn’t pass judgement on anyone. if my friend ships incest and I say that’s my squick, they can respect I don’t wanna see it or hear about it, while I respect their right to ship it.
Wait, I thought that ‘squick’ mainly applies to a fetish or kink that disturbs/grosses you out?
it does! or I guess if I understand your confusion, a specific ship might squick you out because it contains elements that you find…squicky.
like, a ship where person A canonically has abused person B. the word “trigger” might be too strong because you don’t have personal trauma related to that, but the idea of it still really bothers you, enough to call it a “squick”.
