Tell your parents or teacher, But, DO NOT RETALIATE!

Ok.
Today i went on a school trip. We played football and i said to myself that this big guy isnt gonna header the ball. Another kinda strong person overheard and told the big guy what i said. I Said that i said he wasn't gonna header it because the ball was too hard. The other guys like no u didnt. Im like yes i did. Hes like no u didnt. Im like shut up. So he starts pushing me and then slaps me in the head. I didn't retaliate and walked off. Then, he told my mate that hes gonna beat me up on monday.
What should I do?
Please don't say tell a teacher coz i dont wanna =P

Be a man like him and slap him back.
Or use your nails, whatever gives you kids kicks these days.

He wants to beat you up just because you said he wouldn't head the ball? Blimey, not an insult so harsh as that, please!
