Laarping
Old people pretending to be heroes in fake battles. It's like LARP, but with more creaky joints and less magic.
My grandpa dressed up as a wizard and yelled, 'I will defeat you, you puny goblin!'
My grandma tried to fight a fake dragon and tripped over a rock. She said, 'That was a rock? I'll show you!'
My dad tried to do a magic spell and just said, 'Magic is just a word!'
