A way to describe an amazing friend. Someone who is not only very loyal and supportive, but also hilariously sarcastic and unbelievable beautiful (even if they refuse to believe it). If someone is a saturnius, they’re able to not only be there for you in your darkest hour, but also laugh and make stupid jokes with you. Everyone should have a saturnius.

Invented in Borat's movie. It is said, when something great happens.
