Putters love to whistle- loudly. A putter's whistle is often tuneless and full of sentimental vibrato - usually some unmusical version of a wartime number.
Putters can be grumpy and very impatient with young people.

Louis: I putter and then door wedged my GF last night.
Ben: that sounds shitty for her...
