Sleepy Kitty's Irl Threat

Alright, listen up, buttercup. This meme shows some internet hero, 'Sleepy kitty,' making a big, tough-guy threat to find someone and fight them in real life. The humor comes from the fact that this kind of online bravado is usually empty talk, and also because their username is 'Sleepy kitty,' which is a hilariously cute contrast to the aggressive comment. You're probably just as tough behind your keyboard, aren't ya?
