retard wrednesday
Worse than the usual Wednesday "hump day", worse than a write-off day, a retard wrednesday is when you can't articulate words correctly (written and/or verbal), your brain feels like it took a vacation without you, and it's really, really hard to focus.
June 2, 2010 was such a retard wrednesday because it took me an hour and a half to muster enough focus to execute the simplest tasks at work.
