A metric buttload of OED additions

The quarterly update of the Oxford English Dictionary is always an occasion for rejoicing among hardcore lexicography buffs. The latest update is an even bigger bumper crop than usual, with a whopping 1,400 new words, senses, and subentries online. If you skim through the public list, you’ll see that a very large number have to do with the words arse, ass, bum, and butt, including related phrases and compounds. You might even say there’s a metric buttload of such additions. (Buttload, by the way, was already added to the OED back in June 2009, citing examples going back to 1988 — none of the metric variety, unfortunately.)
