give me roasts, something very

Sure! Here are some light-hearted roasts for you:

"You bring everyone so much joy… when you leave the room."
"I'd explain it to you, but I left my English-to-Dingbat dictionary at home."
"You're like a cloud. When you disappear, it's a beautiful day."
"You're proof that even evolution makes mistakes."
"I'd agree with you, but then we'd both be wrong."
"You're like a software update. Whenever I see you, I think 'Not now.'"
"I'd call you a tool, but that implies you're actually useful."
"You're the reason God created the middle finger."
"You have the perfect face for radio."
"You're the human version of a participation trophy."

Remember, roasting is all in good fun, so make sure your audience is ready for a laugh!
