Think twice about that F-bomb in your next talk
Whether you like to admit it or not, swearing is and will be taken as a sign of disrespect or superiority. You (99% percent of us) would not drop the F-bomb in the presence of a new boss, for example, unless you had very good reason to think it was ok. It's similar to the fact that the boss teases subordinates, but the reverse is much rarer. Swearing is absolutely a status strategy, even when speaking to groups. For all the people who claim that swearing is essentially as innocuous as any other speech, and only prissy people think anything of it at all, it would be interesting to see their behavior around their professional or social superiors. There'll always be the people who pipe up to claim they treat everyone the same, and don't know what status is, but on the whole, I'm pretty sure the social implications and power dynamics of swearing show very strong patterns. Swear all you like (I do), but please don't pretend that profane language doesn't have different effects from normal language.
