"It was coined as SIIHP for Stick It In Her Pooper. Very popular on message boards but there is now some merchandise w/ this acronym. This is very popular on LS1.com & LS2.com."
The first instance of SIIHP-related parlance was thanks to bugstud, on
May 15, 2005.
Dead followed it up the same day with a "stick it in her pooper"
post.
And gorgeous a few days later:
post.
Lo and behold, on July 14, 2005, skjonne adds a twist onto the then classic "Stick it in her pooper" by abbreviating it in a thread with a "
siihp"!
Now, if other forums across the internet are suddenly using SIIHP as common parlance, can we now claim that in addition to being on the cutting edge of poker theory and knowledge, 2+2 is actually a linguistic clearinghouse and the new Institute for the Enhancement of the English Language?
