This idiom does a nice job of simplifying the following: 'Wow, I just acknowledged how typical you are being at this moment and because of this, I will give you my approval and praise!'
Jeremy: "They almost came back in the 3rd"
Alex: "I just got 100% on my chemistry midterm!"
Tyler: "Standy the boy!"
Hans: "Shit I just found out my midterm is in 3 hours"
Gordon: "Whoa, are you gonna study for it?"
Hans: "Nope gonna pull a standy"
The Standy Test can be performed to determine a bar's level of standiness. Simply rock from side to side and if your shoulder bumps a person, the bar is indeed standy. If you are squished up to the people next to you like a mosh pit, the bar is very standy and you should probably leave.
Levels of Standy
1. Not standy - you are easily able to find a seat
2. Potentially standy - the bar is starting to fill up
3. Standy - there are no more seats left and you need to stake a claim on a chair as soon as someone abandons it
4. Very standy - You can barely make your way through the crowd to order a drink
Dude 2: "is it busy?"
Dude 1: "it's a little standy, but I got us a couple of seats at a table"
