When you are dancing around in a q shape in among us with a bunch of other people and the imposter kills someone in the dance stack. First coined by wubat in an among us game.
Everyone:PINK SUS
Pink:But wait! It was a QStack Circle Kill
Everyone:Ah shit well I guess we don’t know anymore
an abbreviation of quietly snicker to myself, used as a replacement for LOL because nobody actually laughs out loud when they write this. this should catch on.
