Rule 51

An internet rule which states: For every act of nature or man there will be someone within a short period of time that will attribute that act to a conspiracy theory.

Terrorists kill someone? False Flag! Clouds look weird? Conspiracy to poison us all! Another school shooting? Never happened! Just a conspiracy to take our guns! Government says it is a weather balloon? Alien cover-up!

Corollary: If you can think of it, there's a conspiracy theory about it somewhere online.

Kid 2: Nah bro, hopped on U.D. and did the old Rule 816!

Rule 1129

Rule 1129 states that anything and everything can exist on the online shopping site Aliexpress. Doesn't matter how ridiculous or obscure, as long as you can think of it, it will most definitely be sold on Aliexpress.

'1129' comes from converting the letters in "A", "l", and "i" into its corresponding ordinal number of the Alphabet.

Dude 1: Tf, apparently Aliexpress is a treasure trove for furry costumes
Dude 2: That's nothing compared to what I had found one time. I was bored out of my mind so I looked up gold toilet on Aliexpress and actually found this insane fancy toilet made of 24K gold!!! And it sold for like two grand.
Dude 3: Damn, that's some rule 1129 right there
