The tradition in school when it's someones birthday to sellotape them to a lamp post and then give them a punch on the shoulder.
It's a good hearted tradition
It's Jamie's birthday next week, we should all get together to make sure that he gets his birthday beats!
A traditional act performed in schools (mostly done secondary schools) when someones birthday is grassed around the school and every one punches you on how old you are. E.G you are 15 they punch you 15 times on the arm
Some schools have banned birthday beats from happening
dont tell anyone your birthday date unless you TRUST them OR YOU GET BIRTHDAY BEATS
