Definitions by Nitro8)

A blunt, sarcastic, or decisive expression used to tell someone to shut up; often with style, confidence, or moral superiority.
It's an acronym of "Shut your living hell up", and is considered a less vulgar variant of "Sybau" (the acronym of Shut your b#tch a## up).
This expression was invented by me recently to bypass profanity filters on platforms like Youtube while still delivering the same punch as a very vulgar expression. In short: It's cursing without technically cursing.
"You're just annoying me, so just mind your own business and sylhu🥀"
