Ok, it's time for another word. Now this word I have used in the past, but it was used as an example of a long, smarty-pants word in a conversation with my mother and I finally stumped her - but only for a second. So here you go...
protuberance something, such as a bulge, knob, or swelling, that protrudes.
Used in a sentence: Is that protuberance a gun in your pocket or are you just glad to see me?
NOTE: Of course, he was just glad to see me - wink.
