Inverted Penis Syndrome. Very rare. Pretty self explanatory.
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.
Acronym for inverted penis syndrome.
Katie: Why's your penis shaped that way?
Jon: Oh, I have IPS.
Katie: Oh, that sucks.
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.
