Bring Your Own Sand 

The process of bringing your own sand to a beach themed party (in particular mall beach parties), and is almost always required as the hosts seldom provide any sand. It is often abbreviated BYOSand or BYOS on invitations.

Jackie Chan and Owen Wilson sent out Bring Your Own Sand invitations to their mall beach party.
