Big One

A devastating Earthquake that strikes the San Andreas fault line about every 100 years, last happening hitting in The 1906 San Francisco Earthquake. Most commonly used in reference to a predicted future earthquake.

I think we should invest in some sturdier infrastructure here. I mean, what about when the Big One hits?

one upper

someone who always follows your story with a better one or has things that are waaaay nicer than yours and makes sure you know about it

me: Wanna see the car I just got? one upper: Sure! Yeah, it's nice and all, I'm going to get a Lexus when my boyfriend gets back.

one upper: Your husband's truck is really nice! My boyfriend will probably get one like this, probably newer though.
