Like what the first reply said, my first thought was character x same character lol
For OC x canon, it’s totally harmless. I mean, I’ve never actually done it nor have I talked to a shipper who does it but I take it as a way to announce to the world that you just really, REALLY like that character lololol and honestly? I totally get it. Another reply mentioned that people can get obsessive with it, which is obviously bad, but I don’t necessarily see that as the concept’s fault; people are gonna get obsessed with things, shipping or not ¯\_(ツ)_/¯ as for shipping the same character, I just genuinely find that so hilarious LMAO once again, not harmless! But...why? I’ve only ever seen this sort of ship in a sexual context so I’m just gonna assume that it’s an excuse just to draw the same character twice but please alert me if anyone genuinely ships the same character together because I need to understand the reasoning to that hahaha
I was into Undertale back when it was at its peak popularity and I feel really bad for the amount of hate that Sans fangirls got just because they drew art of themselves with a fictional skeleton. “Cringe” was such a popular word in the 2016 digital art community :/ They were having fun, why rain on their parade?
