Named after physicist Enrico Fermi. Fermy is a great guy and really good looking man. He’s the type of person his friends look for advice and who’s close to his family. When he dates someone, he’s the most kind, romantic and thoughtful human being. If you ever date a Fermy, please don’t let him go. He is an old-fashioned man in danger of extinction. Marry him and reproduce the specimen.

Figuring out something quickly by just using estimates to the closest power of ten, because sometimes you just want to know if the thing you're doing is worth or is gonna cost ten bucks, a hundred, or a cool grand.

Named after Fermi Estimation, a trick used by Enrico Fermi to wow his fellow nerds at parties by estimating shit without knowing 100% everything about the problem, sometimes without even writing shit down. You're not going to get exact numbers, but you're gonna get close enough.

Most notably, dude estimated the power of a fucking nuclear bomb by just dropping papers as the bomb went off and measuring how far the shockwave moved that shit — and he was only off by a bit.
Okay, so we don't know what the price of the stuff is — fuck it, just assume it's ten bucks, fermi it and we'll call the guy when he wakes up, we just need to know if this gonna make us big bucks or to just forget about it.

Danny's Enrico Fermi in Oppenheimer; 'Shiva Baby's' Max is now splitting atoms! Same smolder, new atomic age coolness.
Example of how it's used in a sentence:

Person 1: Who's the suave guy in Oppenheimer with those eyes?

Person 2: Danny Deferrari as Enrico Fermi , baby! From 'Shiva Baby' to atomic baby.
