Ack! is a meme spammed across 4chan boards, participially /tv/ and /pol/. The earliest known use of the meme was on September 8, 2021 by an anonymous user (who, in this case, was the OP of the thread) on /tv/. The thread depicted a GIF of a trans woman, who barely looked like a woman, hanging herself in hellfire. The description simply read “ACK!”. Variations of the meme include /pol/ack and yellow dog (who is meant to symbolize a mod).
