Is this too mean?

Why are you friends with someone that bullies you? Just drop them.

Just say you look like a toad... But I still love you, but you look like freshly mowed grass in the summer rain, but I still love you.. You make me wanna stab my eyes out, but I love you.... CHANGE YA HAIR DUDE

You decide what you have to deal with. If you don’t like this person don’t associate with them. I wouldn’t say anything to them. And I wouldn’t lower myself to their level. I simply wouldn’t have anything to do with them. You are responsible for who you deal with

Next time they bully you say "I'm sorry but someone with disgusting puke green hair has no business calling other people out".

Honesty is the best policy. Tell them that green hair looks fucking stupid.

wtf, tell them their hair looks like ghost ejaculate and that you wish you could find a cliff to jump off of because of that hideous vomit color of hair

Wait for them to bully you again. Then tell the it's "trashy". But expect blows if they're truely a bully.

They bully you?
Don't say anything, let them look like a fool. AND walk away from them. No one need to be around people like that

just point and laugh at them. Then ask them if they caught the person that did that to their head.

Being mean to people who deserve it feels amazing. Don't just come out of left field with it. Save it for the perfect occasion.

you should not really in my opinion say anything bad about it. just let them wear it. eventually if it really is ugly they will probably redie it to look decent.

Telling them the honest thing won't really be considered mean. At least not when compared to their bullying. Maybe you can tell them to colour their face green. To show their true colours as a Ball Python.

Just say I dont like the green hair. It should go.

Yes, bully them back.
