This phrase I believe is from a popular Twitter fic from @mangoball on Twitter that is known around the MCYT fandom/fanbase.
The Twitter fic was titled as “Cheater, Cheater” but is also often called as “Mangoball” for some reason. It is a Socmed fanfic AU featuring Dream, Georgenotfound, Sapnap, Wilbur Soot, Karl Jacobs,
Quackity, Corpse Husband, Badboyhalo and more.
It has gathered a bunch of attention and support for it being
funny and for the ridiculous events happening in the story.
A specific character in this said fanfic which is Georgenotfound always uses ridiculous nicknames for his boyfriend, Dream. And this phrase happens to be one of them. Despite it not meaning anything,
people (and even I) found this
bit funny.
Huge props to @mangoball for having such a creative mind with creating this
amazing fanfic. Loads of people enjoyed it and remember that a huge part of the story is only fictional and for entertainment.
