We used to take a blade of grass , stretch it between our thumbs and make the most hideous noises. It sounded like a small animal being gutted alive.

We lived on a steep hill and our well was close to the road. We were among the last to get plowed out when it snowed, so one time my brother and I hauled countless buckets of water from the well and sloshed it down the hill. It froze and we took our sleds and were able to slide for at least a quarter of a mile.
The man who drove the snowplow and sander was not happy with our little invention, and we were not happy with his spoiling our slide.

Those "Grups" ruined everything.
