You called me what?
Everyone knows a primo insult or two, even if your personal rules of decorum prohibit their usage. But, if you think about it, there aren't many new insults (or swear words, for that matter). The ones you heard from that guy in middle school are pretty much the same ones you hear now.
Let's hop in the time machine and head back a couple of hundred years. These words/phrases might seem rather quaint and out of place now, but back then, they got your attention. "Hey! You scobberlotcher! Thy vile canker-blossom'd countenance curdles milk and sours beer!" Let's examine a few more, shall we?
