It bugs me when people say that something I have written is cliched. So I am always interested in things like Lake Superior State University Annual List of Banished Words, which track words whose usefulness to the English language has come to end. This year's losers include "truthiness" and "i-anything". Can't complain too much about their choices, although I am still fond of the term "boasts" (as she "She boasts an immense set of tupperware.").
And in "researching" this post I came across a list of 1,159 words "not allowed on personalized jerseys at the NFL Shop" (the official shop of the National Football League) because they are considered offensive. I am proud to note that many of these terms have appeared on this site. Moreover, I can testify to the list's utility; there are a few I haven't heard before ("assranger", "axing the weasel") and one or two I don't even know the meaning of ("splittail").
One last comment: "Wigger" is an ugly term. You can say the same thing, but nicely, with "WASPafarian".
