The one that stands out the most for me was in early high school. Probably because of puberty driven hormones, lol.
It was at an inter-school swimming carnival. It was towards the end and everyone was packing up to get on the bus and go home. A guy and girl (boyfriend and girlfriend) had an argument about something and he threw one of her shoes away. She went to retrieve them, and then he threw the other one in the opposite direction. The next instant, her and two of her friends, crash tackled him to the ground and started playfully punching him.
They were all a few years order than me, so I stayed well out of the road whilst continuing to pack up my own stuff.
Not long later, I heard that high pitched giggle/laugh that can only mean one thing.
We were all barefoot as you can imagine, and his girlfriend had made her way down to his feet. The other two sat on his upper body whilst she sat on the back of his legs and went to town on his feet.
He was face down so his laughter was somewhat muffled, but he appeared very ticklish.
The girls were quite merciless and nobody seemed interested in coming to his aid. Maybe because his laughter was muffled, maybe because they felt he deserved it, I don't know. 🤷🏻♂️
What I do know is it went on for quite some time and when they finally let him up, his face was beet red and he looked like he had run a marathon.
He just layed there gasping for breath and only the threat of missing the bus seemed to spur him into getting up.
