Rule #1 

Rocket League term for when two cars ride up against each other nose to nose and become interlocked in a stalemate. Those who break rule #1 are shamed for life and are thus considered menaces to society.

Squidman524: “I can’t help you out, I have to follow rule #1.“

Pezfactory32: “If you break that I’m forfeiting bro!”

“What a save!”

Squidman524: “Fuck!”

rule 787878 

"We're no strangers to love
You know the rules and so do I
A full commitment's what I'm thinking of
You wouldn't get this from any other guy
I just wanna tell you how I'm feeling
Gotta make you understand
Never gonna give you up
Never gonna let you down
Never gonna run around and desert you
Never gonna make you cry
Never gonna say goodbye
Never gonna tell a lie and hurt you"

You have gotten rickrolled
1: hey look up rule 787878
2: you son of a b-----
