(Just a few days ago) I learned a new SE jargon / slang. When mean / nasty ppl (on SE) try to insult you, they often use the word "unclear"

--- as in , [ your question is unclear ]. or (more crafty / careful) [Your question would be clearer if it also included ... (((very vague and unclear suggestion))) ]

"unclear" actually means Moron or Stupid ... but they don't use those words, because those real words can get them in trouble.
