The second has an interesting definition!

<Spiller> Hi, I'll be back in a second.
<Killer> Okay.
*** 20 minutes later ***
<Killer> ...
<Spiller> I'm back.
<Killer> Where were you?
<Spiller> Hang on, back in a second.
*** Killer is offline ***

second 

An indefinite period of time, usually assumed by the listener to be at least 2-3 minutes in length. Speakers use it to affirm that the time will be short without any actual meaning or elaboration, despite the fact that the period will likely be more than 120 times longer than stated (see above).

Person #1: Are you done yet?
Person #2: Yeah, it'll just take a second.

-5 minutes later-

Person #1: *visibly impatient* Okay, are you done now?

Person #2: I said, it'll be a second! Geez, some people.

We do a bad job of only giving a shit about people who are on our team.... I wonder who said that 🤔 oh, wait, it was me. I was the guy who said that thing. I'm the one being quoted in this scenario.

Hym "So, there I sit, in 'Everyone is working their hardest world.' I'm jacked. I'm working my hardest. But wait a second! People don't like all of the things I've said. They like some of them. So they take those things and say them as though they weren't scrolling through Urban Dictionary in-between working as hard as they can. They're all yoked. A director is there. He reads a compelling soliloquy. Decides to put it in his movie. He doubled up on his HGH injections today. His muscles are bulging. Everyone who both reads the book and watches the movie knows where it came from..... I fell asleep.... But they are all working their hardest and nobody says anything. They are all cut. They've been doing two-a-days."
