i will full smash you bro

A threat that is used predominatly by people who are definately not going to inflict any damage of any kind upon you. Found mostly to be used by a vietnamese and a half asian kid residing in Melbourne, both who have done plenty of smashing.

Jimmy: I will full smash you bro!
Jules: I will full smash YOU bro!
(begin pushing each other)
