Originates from a rite of passage taken by the ancient warriors Ba and Edo. Now encompasses a drunken ramble, of a nearly pointless nature, across London. When one arrives to ones destination one must incessantly high five the other partakers until their hands hurt, while chanting yes my son (this can also be called a my son battle). On a 'my son adventure' you cannot take a cab and must find the most potentially irritating route home, stopping off at various fast food establishments and cornershops. it is a banterous journey of discovery.
That My Son adventure was sick. YES MY SON, YES MY SON, YES MY SON!!!!
