The act of defecating in a 5 gallon bucket and slamming the bucket over your best friend's head. This results in a frenzied motion of your friend trying to remove the bucket from atop his head. After he successfully removes said bucket, you punch him in the face and say "you've just been Bucket Punched."
"Hey bro you see that chinese kid get bucket punched in Home Ec the other day?"
