No idea. Maybe, a natural-born talent for expletives in
any language! 
Anyways, I love my colleagues who swear. They are usually
the more sincere peeps. That's probably why I like to watch
Gordon Ramsey at work too... he's so frank, and he swears like a
sailor, but he's often right and very sharp in his judgement of
people. People who swear at work are more likely the
roll-up-your-sleeves and just start working kinda wholesome
folk.
Swearing is ok for me when it comes to happy, back-slapping
moments.
But if we're doing serious things, like say operations out at
sea, I don't like to use use expletives and I don't like to hear
it.
It clouds intentions at the most crucial moments.
