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 user DaFuq!?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 "Å kibidi", 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.
