eat the corn - A phrase you write on the bathroom wall to make people laugh

A phrase you write on the bathroom wall to make people laugh and maybe vomit.

I wrote 'EAT THE CORN' in the bar bathroom and got a free shot for my bravery.

The message 'EAT THE CORN' was so bad it got a warning from the bar owner.

I scribbled 'EAT THE CORN' on the crapper wall and got a high five from the janitor.
