a spooner - You mix up the start of two words to make a silly mess of yo

You mix up the start of two words to make a silly mess of your speech. It's stupid and usually happens when you're too dumb to think straight.

I said 'flicky beans' instead of 'flicks beans' and my teacher said I was a spooner

I said 'bithy wick' instead of 'witchy bick' and my friend asked if I was high

I said 'flobber wick' instead of 'wobbler tick' and my friend laughed at me
