Sniveling Anus Syndrome

A very uncommon syndrome acquired from constant and rigorous wiping of the asshole. Most common symptoms include (but are not limited to): bleeding from the anus, discomfort when sitting down, a little voice coming from your rear end telling you to eat more Chipotle, and uncontrollable desire to dress and act like Joseph Gordon-Levitt did in 500 Days of Summer.

Me: I just can't stop bleeding from my asshole doc.

Doc: Have you been watching 500 Days of Summer?

Me:...What if I have?

Doc: I'm afraid that you have Sniveling Anus Syndrome.
