A satirical dialect of the English language, gigglespeak includes gross misspellings and grammatical errors. Very similar to jeffk, although gigglespeak preceeds jeff by several years. Possibly had its origins with B1FF, an alter-ego (most likely) of Kibo's. It is better to define the dialect by example:

DUED!!!!1! HALE ME, FOR I HACE POSTED TEH GIGGLESPEAK NODE AT TEH E2!!!!!!!1! I HACE NODE-NESS!!!!

Gigglespeak can be found most often in alt.fan.karl-malden.nose, and other members of the Malden Family of Newsgroups.
