1. Intrepid Posting Syndicate - In 2004 a crack message board posting unit was banned by a overzealous admin for a crime they didn't commit. These men promptly escaped from the SOE boards to the OG underground. Today still wanted by the admins, they survive as posters of fortune. If you have a problem. If no one else can help, and if you can find them, maybe you can hire, The IPS Team.
Dude, IPS totally pwned those boards.

Introductory Physical Science, a course involving far too many experiments but several amusing acids.
In IPS today, I stuck my finger in a test tube of acid and the teacher laughed at me.

Involuntary Pig Snort
The sound that a person often makes while laughing hard and breathing in at the same time. This sound is just like the sound of a pig snorting through their slop at meal time.

The sound often made when someone says they are LMAO.
