Broken Vessel, a character from the popular video game "Hollow Knight", sometimes can be referred to as "Gloopie-Kin".
This nickname is a reference to the big orange goo on Vessel's head and their Dream variant, Lost Kin.
The term "Gloopie-Kin" was initially started as an inside joke in someone's DMs.
A: Bro, someone nutted on my backyard.
*it's just some intense snowfall*
B: Not funny didn't laugh.
A: Ya know what IS funny though?
C: wat
A: Nah, man, this is Gloopie-Kin!
