Larping in Gravity Falls

The first time I heard the word "larp" was in Gravity Falls. Soos explained to Dipper that he liked larping, or "live action role playing" with a group of friends. I think his group was called FCLORP instead of just larp, because it stood for Foam and Cardboard Legitimate Outdoor Roleplay. If I remember correctly, there was a scene where all of the larpers wore cardboard armor and acted out a battle or something. Anywho, as larp has become a popular term on social media lately, all I've been able to think about was that gravity falls episode. Does anyone else remember this?
