Used to display displeasure of having to do something you don't want to do.
Ack! Was the sound Bill the Cat made when hacking up a furball, in the cult comic, Bloom County, which Berkley Brethead drew.

Get the Ackmug. 
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!

Get the -ACK!mug. Popularized by Berkely Breathed's disturbing cartoon character "Bill the Cat" of Bloom County fame (later became Outland). It is the product of the random misfirings of a braindead individual who wants to say something intelligent but seems completely devoid of any grey matter. It is frequently followed immediately by the word "thptptpt", which is produced by flatulations of either the lips or some other sphincter.
You may also hear this exclamation muttered by hung-over frat-brothers when they first wake up.
You might also hear this word from time to time in an overcrowded senior retirement center, with nobody noticing it is even being said.
