Friend's Basement Item

Okay, you knucklehead! So, you found this really wild thing in your pal's basement, right? It looks like some kind of homemade mace, like a weapon from a video game, but then BAM! There's a butt plug on the end of the handle! That's the funny part, you slowpoke. It's totally unexpected and a bit rude, which makes people laugh awkwardly. It's like something you'd see in a weird online 'item shop' because it's so bizarrely put together. Your friend has some... interesting hobbies, you know that, right?
