Sentinelese 

The Sentinelese is the tribe of North Sentinel Island. They are the last hunter-gatherer tribe in history and will lash out and attack outsiders. Basically, you shouldn't mess with them.

Jessica: Hey, have you heard about the Sentinelese? I've heard they're the last hunter-gatherer tribe in history!
Brandon: Yes, they live in North Sentinel Island and will lash out and attack outsiders. You shouldn't mess with the Sentinelese, Jessica.

Anyone with this syndrome is automaticly a pro gamer, and pretty good at any game. The only downside is that you are pretty bad at defending pack and carno cave and will lose it within a day.

Ur in sentinels? Wow you must have the Sentinels Syndrome.
