Google Correlate, it is anyway. If you go to the site, you can type in any search query, and (if it is popular enough to have enough of a hit history with Google), you will get a list of other searches that have a high correlative search history with yours.
Typing in "Google" came back with "kratom" with a correlation value of 0.9807.
What is kratom? It's a "trendy" medicinal herb. So, I guess that Google is as correlatively as trendy as a medicinal herb. (Or is it the other way around?)
