More recently used to unintentionally irritate people who prefer straight forward answers. Literally, "something is urgently wrong but instead of me just immediately telling you, you must figure it out yourself in the amount of time it takes me to make this sarcastic and unhelpful remark."

Can be typed as well.
Example, this used to be proper protocol in an urgent situation--
Bob: "Joe, watch out for that large pothole you seem to be unknowingly driving into."
Joe: (avoiding pothole) “Thank you for your timely and straight-forward warning. I appreciate you using the first sentence after you were alerted to this danger to tell me about this pothole, instead of uttering a one-worded, useless phrase.”

Modern protocol, same situation--
Bob: (sarcastically) "Um..." Joe: “What?..... What?” (car drives into pothole)
Bob: “Wow, good job.”
