-ACK!
A meme originating from 4chan and soyjak.party around late 2021 used to deride another user by indicating that they're suicidal, e.g. that they were hung in the middle of typing their sentence. It immediately ends the quoted sentence, is often put in place of vowels near the end of a sentence for maximum onomatopoeification, and in addition it's almost always in greent-ACK!
