Phallographics 

the pictorial representation of a phallus, or a depiction relating to or resembling a phallus

For some reason, I don't know why, I used to have this thing...where I would...like, kinda...sit around all say and draw pictures of dicks. My therapist called it phallographics.

I drank lots of water today and then practiced my phalligraphy in the new snow. Knowing cursive sure pays off!
