ACK!

An onomatopoeic description of the act of suicide (by hanging). The sound is similar to the exhalation of air caused by a rope tightening around someone's neck, choking them.

Commonly used by 'teens to insult valid and xholsome trans xisters, but can be applied to anyone you think should rope.
Usually used as if cutting off the previous sentence, as shown in the example below:

Troon: "My boss just sacked me for being trans!"
'teen: "My boss just s-ACK!Join the 41% tranny"
Troon: *acks xhemselves after gooning to' p one last time*

Ack

Short for “Acknowledged.” Mostly used by military personnel to quickly confirm that they received the sender’s note, email, task, order or request.

“Ack” can also mean “Yes; Ok; Got it; I’m on it; or Confirmed.”

No Ack

Associated with bad behavior

Definition #1 Don't act like that

Definition #2 stop trying to show out

People like to drive on the backside of Haleakala /Hana... Roads are one lane, gravel and drop off into the ocean at points... It is the locals way of getting out into the city.. So it is seen as disrespectful and dangerous... Thus discouraged

Someone hacked the computerized road closed sign to say:

Stay Out Fakas

ACK!

A slur used to mock trans people. The word ACK, originating from 4chan, it imitates to the sound of a popular far right meme of a cartoon where a transgender person hangs themselves thus makes fun of the high suicide rates within the trans community.

ACK! is thus not a slur to name trans people, rather a word for suicide of a trans person, used in a manner to mock the trans community.

*Comment thread of a trans influencer*
Far right commenter: "hope you ACK! later today"
Far right commenter 2: "hope the troon ACK!s"
