marshmallow fingers

What happens to the fingers of amateur guitarists who play for three hours in a row without a break. Their delicate wittle finger tips just can't handle those metal strings and they get all puffy and tingly...and look and feel like marshmallows.

Larry: Dude, I played the guitar for like 3 hours today!

Rick: OMG! You have marshmallow fingers...

Larry: I know. I guess I need to man up a little and practice more, right?
