Painterbation
When you stick your weenie in a can of paint and whip it across the wall like you're trying to impress a kid at recess.
My uncle did this in my mom's living room and now it looks like a raccoon threw up in a paint factory.
She called it 'the ultimate masterpiece' and it was just a bunch of red splotches.
He said it was 'modern art' and it was just a blob of green and a single hair.
