When someone asks "What's up?", you can respond with a humorous twist to add some fun to the conversation. Here are some funny responses:
"The sky, but I'm trying to convince it to come down and hang out with us."
"Not my GPA, that's for sure!"
"Oh, you know, just standing here, wondering why the ceiling is always up and the floor is always down."
"Not much, just trying to be taller. I heard the air up there is pretty great."
"Well, I was about to chase my dreams, but they're too fast for me, so I settled for walking to the fridge."
"Trying to decide if I should be an adult or continue binge-watching Netflix. Netflix is winning."
"Just attempting to become a master in the ancient art of doing nothing."
"Avoiding responsibilities like a pro, you know, same old, same old."
"I'm currently in a battle with my alarm clock. I'm losing."
"Life, liberty, and the pursuit of snacks – that's what's up!"
Remember, humor can be subjective, so consider the context and the person you're talking to when delivering these responses. A good laugh can brighten anyone's day!
