What happens when you use a keyboard (on a cellular phone, regular phone, computer, typewriter, court reporter device, piano, synthesizer, organ etc.) and you keep on hitting "between the cracks" of the keys. A play on "butterfinger" and "gutterball", and the dictionary meaning of "gutter".
Why do I keep on getting "ansewr" for "answer"? It must be my gutterfinger!

My ex is such a gutterfingers, he's always typing stuff like "It's hard enough to get them to take penisillin" and "That would be bad, wouldn't tit".
