ka'nap"pa. n.
A small appetizer that consists of a spread (like paté, caviar or cheese) on a cracker or thinly sliced toast. This is finger food -- you're supposed to eat it in one bite. Please don't try to bite it in half or nibble daintily around the edge like a field mouse because it doesn't work. What inevitably happens is that you'll spill food all over your clothes and make a spectacle out of yourself. If at all possible, you should enjoy your food. I'm sure Miss Manners would agree.
