That doesn't make any sense. If he or she is actually fit in that category. Why would he or she stand up without a reasonable reason. It's stupid and worthless. The only thing they might stand up for is if they think its fun or your interesting in a way.
You can put it that way cause you have never heard of it. It have an opposite effect, if you don't actually know how to speak that language but tried. Its really irritating. I may be delusional but I'm not retarded.
