The common acronym refers to getting someone a tomato.
The origination of the word "Skibidi" is originally from a misheard lyric in a viral song. The viral song is "Dom Dom Yes Yes" by Biser King. The original lyric was not "Skibidi" but "Shtibidi". From there on the word increased in popularity until the series "Skibidi Toilet" appeared on YouTube. This is now used mostly by Generation Alpha. It's now used as an adjective which can mean anything because it has no true meaning. Most would use it to describe something funny or "cringey"
Tim: Hey John!
John: Hi Tim!
Tim: You're so skibidi!
