Someone who will overdo something, example being a roleplay, and then they feel extremely proud of it, even though it turned into a massive mess, the people who created the mess wouldn't care, as they feel they had accomplished something out of that
example
"Bro shut the literal fuck up you LARPer"
or
"Man, you didn't have to LARP the whole situation"
Your a larp, Your larpin as someone.
