The practice of dipping your penis into paint (watercolor paint is the safest) and then painting a picture with the end of your dick. Some of the best pictures are when your lady does the painting...
For the first time, last night my special lady and I did some penis art, which she wanted to take home and have framed.
drawing penises on EVERYTHING, and I mean everything because you are immature and it's funny as crap. This may also include making penises out of loose leaf paper.
Dude check out the 30 foot penis someone drew on the classroom wall! that's some hella penis art!
