To be so angry that your outward appearance takes on a constipated look.
Usually occurs at
work following some ridiculously
stupid decision made by a complete retard (or an entire team of retards). You will tend to be caught sitting at your desk with a far away thoughtful look but you're completely
red-faced as if trying to push a stubborn turd out of your ass.
Christian: What the hell is wrong with
Paul?
Lee: Oh he was told he's going back to
work the phones at the helpdesk for a few hours so he's angerpated.
