Skibidi ballz is a rare type of disease which is caused due to seeing a level 9 gyatt (gyyyyyaaaaaaattttttttttttt) and your lil wee wee starts getting summoned and then ur ballz shrink to form a toilet shaped ball bag
The word "Skibidi" originated from a scat singing verse of the song "Dom Dom Yes Yes" by Biser King and was popularized through a series of short form YouTube videos by userDaFuq!?Boom!. In linguistics it is commonly referred to as a nonsense word, because it conveys no actual meaning and is used solely for phonetic nicification, mostly sarcastically. Although it has no definite meaning, it can change that of a sentence and its effect varies slightly based on its context.
In the original version of the song it is pronounced as "Škibidi", which sounds like "Shkibidi"; this original pronunciation is found mostly in the Middle East and eastern Europe, though usually less frequently than the english adaption of it.
