Have you ever been in the middle of a conversation, and you really don't want to be talking to that person? Then 1-2 sentences into them blabbing to you about something you already know, the only word that pops into your head is Douche, and it's pretty much all you can do to contain it and not say it out loud to that person?
I don't know, maybe it's just me. Or maybe it's just the doches' around me????
