Mad Radd
A Mad Radd is when someone contacts you just to annoy you, even though you're clearly not available.
Hey, I'm going to the store. (Even though you're stuck in your room with your headphones on.)
Hey, I'm going to the movie. (Even though you're stuck in the middle of a math problem.)
Hey, I'm going to the park. (Even though you're stuck in your bed with a broken leg.)
