Anything used by guys to shield oneself from the rain...bags,boxes,papers etc. Anything other than an actual umbrella.
I'm using this box as my Manbrella.

A large umbrella, usually then length of a walking stick and too big to be carried in a womans hand-bag. When open it is able to cover more than one person comfortably
I prefer to use a manbrella instead of those little umbrellas some women carry with them
