A fork of Rural Dictionary
A nickname for someone who is really cool. Though it may seem like an insult to others who are unaware, you can use it to show your appreciation for someone. And no, this has nothing to do with "Moss Man". Despite the MR at the start of it, this term is gender neutral.
Person A: hey do you want to go to the beach tomorrow Person B: yeah that sounds great, as long as I can invite 'Mr. Moldy Moss Man'
