eating a dirty tomato
Looking up a word just to see if it's something stupid and then pretending you knew it all along.
I looked up 'puddle poet' and it was just a guy standing in a puddle reading a poem. I told my friend I knew what that was before he told me.
I looked up 'banana whisperer' and it was a guy talking to a banana. I said I knew that one already.
I looked up 'dirt muffin' and it was just a muffin with dirt on it. I said I knew that one from the beginning.
