Plural of curling: instances or examples of something curling up, or the sport of curling played on ice with special stones.
From 'curling' (the act or sport of curl, or gerund of 'curl'), pluralized with '-s' to indicate multiple instances or examples.
Curling as a sport probably got its name from the curved path the stones make sliding on ice, and it's one of the few sports whose equipment ('stones') literally demonstrates the word's physical meaning.
