ability to draw stick figures and genitals(this is important)
timer
alcohol (if you so desire)(strongly recomended)
Step1
Divide players into teams. It is best to draw names out of a hat or bag so as not to hurt anyone's feelings. (however, if you can rig this process in any way, do so. you always want the bast drawers and guessers on YOUR team).
Step2
Once in your teams, split up with pen and paper to write ideas of things for the other team to draw. It is preferable to choose the most profane items possible ie. yeast infection, double penetration, multiple orgasms.OR items that will be very difficult for others to draw such as specific days of the week. but always remember: the DIRTIER the BETTER.
Step3
Now your teams will reconvene at the drawing board. choose who will go first. one player will draw and the rest of their teammates will try to guess what they are drawing. Remember not to use letters or numbers in your drawing. each team will be constricted to a three minute time limit.
Step4
At this point teams will start to become agitated. Take a sip of your drink and start yelling. everything is more fun when you're yelling and calling people names.
Step5
There is no specific end for pictionary the fun way. play until everyone is passed out :)
