P and F Syndrome
When you confuse P and F so much it's like your brain is stuck in a blender and your mouth is trying to escape.
You say 'puppy' and it comes out as 'fuppy' and your neighbor thinks you're talking about a new dog breed.
You try to say 'fry' and it becomes 'pry' and your friend thinks you're doing a magic trick.
You say 'piano' and it sounds like 'fiano' and now you're the weird kid who plays a fake instrument.
