A good friendly diss roasts a habit the person already jokes about, like running late, bad parking or burnt toast, and never their looks, weight, race, religion or body.
Below are 40 clean lines, all our own, written for this page. Swap in names and details to make them yours. Then drop them into the free lyrics step of an AI rap battle video, which costs $9.90 once you turn it into a video.
The three rules of a friendly diss
- Punch at habits, not at who someone is. Lateness, cooking, driving, screen time and gaming skills are fair game.
- Use things they already laugh about. The best roast is the one the target quotes back to you.
- Nothing private. No exes, health, money troubles or anything they never shared in public. No slurs, ever.
For your best friend
- You said "five minutes away" from your bed again.
- Your playlist skips more than you skip the gym.
- You lost at Mario Kart to a kid who can't read yet.
- You still owe me twenty bucks from 2019. Interest is a bar.
- You give life advice from the couch, in pajamas, at noon.
- Group chat legend, real-life left on read.
- You plan the trip, then fall asleep before the airport.
- Every story you tell starts with "okay so this is crazy."
For your sibling
- Mom's favorite? Bro, she saved my drawings, not yours.
- You borrowed my hoodie in 2022. It lives with you now.
- You did the dishes once. You still bring it up at dinner.
- Your room's a museum of cups.
- Calling dibs is not a legal system.
- You took the last slice and said, "Who ate it?"
For a coworker or your boss
Only if they're in on the joke.
- This meeting could've been an email, and so could your rap.
- You reply-all like it's your cardio.
- You say "quick sync" and steal my whole hour.
- Your calendar's full, your to-do list is fuller.
- Camera off, mic on, crunching chips like a podcast.
- You "circle back" so much you should be a roundabout.
- Printer jammed again, and you looked at me.
For your partner
- You steal the blanket, then ask why I'm cold.
- You say "I'm not hungry," then eat half my fries.
- Fifteen minutes picking a show, two minutes before you sleep.
- You parallel park like you're scared of the curb.
- You set eight alarms and wake up to none.
- You call it "organized chaos." It's just chaos.
For your grandma or parents
Keep it warm. These land best when they're true and loving.
- You text in all caps like the phone owes you money.
- You send good-morning pictures at 5 a.m. with glitter.
- You say "I don't need anything," then point at the store.
- You ask if I'm eating while I'm literally eating.
- You call the TV remote the clicker and lose it daily.
For your pet
- You knocked my phone off the shelf, then judged me.
- You bark at the mail like it insulted your mom.
- Rent is due. You've paid it zero times.
- Three hundred bucks on a bed, you sleep in the box.
- You eat like you've never seen food, every single time.
- You chase your tail and still don't win.
- You stare at walls like they owe you treats.
- You shed on black clothes like it's your job.
How to put them in a battle video
- Open the AI Rap Battle page and pick an opponent: a cat, a dog, a grandma or a boss. You upload one photo of yourself. The opponent is an AI-made character you can rename.
- Paste two or three lines into What's it about?, pick the roast vibe and tap Write my lyrics. The AI writes your verse, the comeback and a shared chorus. You can also swap in any line from this list by hand.
- Make the song. You choose your voice and the opponent raps in the other one. The song is free to hear (your first song each day is free).
- Pick 15 seconds where you both rap, add your photo and pay once. The video is ready in about 5 minutes.

Only want the words?

FAQ
Can I use these lines for free?
Yes. Use them in your lyrics, your captions or a toast.
Will the AI write mean disses?
No. The roast vibe teases but stays affectionate, and lines that cross the line get refused.
Can I roast a real person by name?
Only a friend or family member who agreed to be in it. No celebrities, no real rappers and no minors.
How long is the battle video?
15 seconds, vertical 9:16, with sound, both rappers in one shot.
Is the diss track generator the same as the battle video?
No. The generator gives you lyrics only, for free. The battle video turns lyrics into a two-voice song and a video, paid per video.
