if you have a BULLY class mate what should you do kick his butt or what
what's in your mind

Umm..
That is something you're not supposed to do.
Normally you're told to tell an adult (parent or teacher) and they can deal with it.
Even though that might not always work, it's what you're supposed to do.

i would flying karate kick him

You shouldn't Hurt him. It'll just lead to you getting in trouble, Not the bully.
You should tell One of the Teachers, In school. Or Your Parents.
Not hurt the Bully.

I'll flip flop him to his mamma

well i was bullied at scool.
i handeld it with sports.
i play waterpolo to use it as a steam unloader for me.

best way to handle is to talk about it with your teachers and parents.
maybe even the parents of the bully.

dont kick him or hurt him. that will make your case a lot weaker against him.

I would say report the bully. He learns his lesson, if he doesn't, pwn him

I think you should fight back
Bullying is a form of the person learn to defend yourself, then children should learn to defend themselves from aggressors of bullying to become full adults.

i would just do what he does to me, if he insults me, i insult him back, if he tries to hurt me, i would run away :P

Beat him or her up
If you don't you have to suffer i speak from experience
I have been bullied for years and at the day before the last day of school of my primary school i beat up my bully and the last day he avoided me because he was scared of me
Now i am in secondary school and now everyone bullies me it just becomes a part of life
Listen to music and ignore them meet people and seek protection in a close group of people who care and protect each other

sometimes words dont work . stand your ground and push him away if comes back swining its self defence all you did was pushed him away because he was bothering you

Theres this kid who plays dumb(and really just is dumb) and id like to kick his booty. But i dont want to risk getting in trouble. What should i do?

hahahahahahahahahahahahah funny

Yeah I would not hurt the bully like I learned in school walk away or if gets more serious go tell a trustable teacher or an adult because if you hurt the bully too you can get blamed for hitting him which makes you and the bully in trouble.

i think you should talk to your principal and i think he or she will act on that,you can also talk to your parents and tell them that you have been bullied.
