Feign is a synonym of "pretend". But the word I referred to meant "to pretend to be full of work when the situation is the contrary", e.g. "to have your desk full of papers and feign you are too busy to do anything else"
There is a word in Dutch, made up by a Dutch writer in 1954, that means about the same thing: http://nl.wikipedia.org/wiki/Epibreren. If I'd follow the "conventions" of similar words that are translated to English, you could probably say "to epibrate" or "epibrating".
