@msolga,
By the way, this is one of those instances where Wikipedia is wrong, IMO. My own observation (which may or may not be correct) is that the Tea Party movement was first derisively referred to as "teabaggers" by bloggers who knew full well what "teabagging" meant and thought it was hilarious that Tea Party people
didn't, and accepted that label willingly.
It then gained wider usage, some ironic (knowing the original meaning) and some not.
