In sign language, we use the concept “done” or “finished” to mean that something is completed, as well as to signify that “it’s all gone.”
In Deaf culture, one might sign FINISHED with one-hand to signify that they are in on the joke and “finished with it,” almost like the hearing equivalent of “cut it out!”
