The new "hip" thing to say in a Facebook status update. Wildly used out of context by students and young English people in an attempt to stand out from all the everyday statuses that appear on the proverbial news feed.
CORRECT example. "That awkward moment when you're facing an old flame/work colleague on a train/bus and attempting to avoid eye contact."
WRONG example. "That awkward moment when you realize you've woken up late for a lecture"
That's not awkward, that's just laziness.
