Awwww it actually means love to a bunny

How big is his cage, has he got a lot of space to run around?

Telling him off won't really help. Rabbits are prey animals so you need to earn their trust so they don't see you as a predator. If they get scared they are more likely to nip more.

His hormones may be kicking in and once neutured a lot of rabbits calm down.

If it's just a gentle nip, that's just grooming behaviour usually. They don't know they're not grooming something with thick fur! If it was a proper bite you'd know as it would likely cause bruising, bleeding, and you'd have a grumpy growly bunny on your hands!

At 4 months the bun will be starting to reach sexual maturity and naughty behaviour such as peeing on things will start to happen. You can't punish a rabbit for bad behaviour though - if you do that you'll just end up with a very angry rabbit!
