Sanscest

Yes, the Sans of the funny song Megalovania. Sanscest is the name that the fandom gave to the ships between a Sans and another Sans from different universes/ AU's

-Hey, i really like to ship Sans from Underfell x Sans from Underswap-

-Wait, isn't it Sanscest?, because they're both a Sans but from a different universe-

-Well, Jeremy, yes it is, if saying that they're both a Sans wasn't obvious that is Sanscest

sanscest

Sanscest is a type of yaoi shipping that refers to a pairing between two Au sanses. Mostly seen on an explicit perspective.

A: yo what's your otp sanscest ship?
B: I'd say errorink...but I have sooooo many!
