The occurrence when a friend is denied alcohol. Usually happens when there is not enough to go around, especially to that one person that always mooches.
Ryan was partying with his bros, when Luke showed up with none of his own alcohol. Luke was immediately put on brohibition for the remainder of the night because of his previous alcohol mis-happenings.

When a bro decides that it would be best not to drink brews or consume alcohol with his bro's and it is most easily achieved with a lame excuse. Bro-hibition has and always will be frowned upon in the world of Bro-therhood.
We were hanging out drinking having a good time when we decided to invited our bro-ther over to down some brews, when he replied with a half ass excuse that did not justify not drinking. Wow that douche bag really knows how to commitment "Bro-hibition"
