Astronomic bg 

a French slang compliment, usually used to let one's friend know how cool he is.

'Astronomic bg' literally means "Good-looking guy from another galaxy" (bg = beau gosse in French)

I really like Esteban. He definitely is an astronomic bg.

Astronomical 

A very large object, usually meaning huge, big, or gigantic. Many people use it in a sentence that has to do with a memorial statue, or just a large object in their house, or at an amusement park.

The sequoia tree was so astronomical, it was over 52,500 cubic feet!
