SEOmoz list of SEP jargon

I frequently wonder what the hell other bloggers are talking about when they use the latest SEO buzzwords (and I’m not always convinced they know what they’re saying, either). SEOmoz has compiled a handy and huge glossary for these terms. They include a few I’ve never heard of, like:

• astroturfing (the opposite of full disclosure) attempting to advance a commercial or political agenda while pretending to be an impartial grassroots participant in a social group. Participating in a user forum with the secret purpose of branding, customer recruitment, or public relations.
• keyword cannibalization The excessive reuse of the same keyword on too many web pages within the same site. This practice makes it difficult for the users and the search engines to determine which page is most relevant for the keyword.
• LSI(Latent Semantic Indexing) This mouthful just means that the search engines index commonly associated groups of words in a document. SEOs refer to these same groups of words as “Long Tail”. The majority of searches consist of three or more words strung together. See also “long tail”. The significance is that it might be almost impossible to rank well for “mortgage”, but fairly easy to rank for “second mortgage to finance monster truck team”
• SMWC (Slapping Myself With Celery) indicates an extreme reaction similar to a “spit take” but more vegan-trendy. Often combined with other exclamatory acronyms. - WTF/SMWC, or perhaps ROTFL/SMWC.

“Slapping Myself With Celery”? I’m not sure I’ve ever experienced that feeling, but um, good to know if I ever do.
