Moving or wriggling around in a wild or uncontrolled way.
Spurgalling can be funny or playful, like when kids are playing and moving around a lot.
Examples:
The kids were spurgalling around in the playground.
Stop spurgalling and sit still!
The puppy is spurgalling all over the place.
The monkeys were spurgalling in the trees.
She was spurgalling so much, she fell over!
I love spurgalling around with my friends!
