I've already seen some people simply calling him "45."

Someone on my flist keeps referring to him as [varying ridiculous noun beginning with a D] 'Twat', and while I sympathise - and am conscious that I'm not an American so am affected by him much less, I'm starting to wonder how long I can stand the misogynistic language. (Is it a common term in American usage? I had it in my head that it's a Britishism). 45 seems a better strategy to my mind.
