This actually originated from Be-mag message board by a bunch of kick ass aggressive rollerbladers who own you and your mother. I will credit the user BMV aka Hatecrew Deathroll who is said to say the first instance of siihb on the internet and in history.

SIIHBAP 

A term that means Stick It In Her Butt And Pee. The origin of the phrase is unknown.

Despite the GTF spamming this definition, they did not invent it as admitted by the first member to use it at the GTF and it's also pretty much guaranteed not to have originated at the bmxboard.com. Neither site should be trying to use this definition to boost their user count. If they continue to, then SIIHBAP them.
