Laarping
When old people dress up and go around fighting fake monsters like they're still cool. It's like LARP, but with more bad breath and less magic.
My grandpa wore a knight costume and yelled, 'I am the mighty Sir Chuck!'
My grandma tried to fight a fake troll and said, 'I'm not done yet!'
My dad tried to do a magic spell and just said, 'Abracadabra, I'm a wizard!'
