IFP (Internet [s]relay[/s] fourm programing)!
Quick little thing based off of IRP (Internet relay programming) You create a program (Aka plain english thing you want someone to do) and someone else 'executes' it.
Here is a example
Bob: Changle a lightbulb
Bill: Error: Too lazy
Jane: Sing 99 bottles of beer
King: Eat cake
Bill: Certainly, none for you, by the way.
Generally, its kinda like givinga command and the next user either does it or not.
Funfact: "Say this exact post" is both a quine and a DDoS worm
