2.
Something which turns out to be extremely stupid, pointless, or disappointing to say the least. A twist on the adjective 'lame', used more by the cool kids.

Can be used as a synonym for 'ghey' also.
Guy: Hey, how's you're day been?

Girl: Pretty rubbish, I had the most boring lecture today, and then when I went to the cinema, the film I wanted to see wasn't even showing. They were both so lame-oh.

Guy: Yeah, that's purdy damn lame-oh.
