Idk man, I'd rather just have a poster that says:

REGARDLESS OF AGE, WEIGHT, OR GENDER

A PERSON CANNOT CONSENT WHILE INTOXICATED

YOU WILL BE CHARGED WITH RAPE,

YOU WILL BE BARRED FROM HIGHER EDUCATION,

YOU MAY SERVE PRISON TIME,

AND YOU MIGHT EVEN BE FORCED TO LIVE IN A

SEPERATE NEIGHBORHOOD AMONGST

OTHER SEX OFFENDERS FOR THE REST OF YOUR LIFE.

In big bold red letters on a white background. If the people seeing it don't understand after that, then they're a lost cause.
