Pardon my (economic) language
CEO of Irish low-cost airline Ryanair Michael O'Leary grimaces as he speaks during a press conference, on March 29, 2012 in Brussels. O'Leary, named in the Bloomberg article, is particularly well known for his coarse language.
Apparently, and this kind of stands to reason, the use of profanity by CEOs varies with economic conditions.
Bloomberg actually went through and did a word search of earnings call transcripts for the past 10 years. Profanity peaked in 2010, dipped a bit, shot up again in 2012 and has been declining ever since.
I know you want to know what the words are, but I really need my job.
There's a chart that'll give you the details, though:
