Bathroom Walls: The Original Message Board

Before the birth of "OP is a faggot" and memes, the best way to spread vulgarity and hate to a broader audience was to scribble your message to the world on the walls of public restrooms. Before smartphones and Angry Birds, all you could do during an unplanned deuce was stare at the walls, in most cases a plethora of ongoing conversations. Limericks, mom jokes, cave drawings of penises, they were all on semi-permanent display for an audience held captive by bodily function. If you were lucky enough to have a writing utensil, you could cast upon the world an unsavory message of your own to amuse fellow shitter patrons. If you were really lucky, someone would continue the conversation by adding a witty retort.

Behold this modern example of bathroom wall art: "2 inches of hard Dick". And then, as we can see, RE: "2 inches of hard dick": "In your moma's(sic) mouth."
