They're pretty much what you'd expect:
"Like" is #67, though probably much higher in some vocabularies (I know I use it all the damn time). "Fuck" is #5598, though since this program is based on the British National Corpus, I expect that's a low ranking due to the fact that people tend to say it a lot more than they write it. On a note of pure blog vanity, "bourgeois" and "nerd" are #7063 and #70675, respectively.
Go try it out; it's fun!
