YES! MBTI性格类型
背景
Can express extreme pleasure (such as charging up a boarding ramp and gaining superpowers), but it can also be used by Large Hams as a way of expressing joy, agreement, or — if the ham is extra large — the reply to a completely mundane yes or no question. Also can be used as a response to obvious or rhetorical questions in which cases it means, "Geez, you really think so, Sherlock?" or "Just do it already!" It can be uttered quickly or drawn out, as long as it leaves an impression of some sort. Can be substituted with "yeah" or "yay".
