Used when describing a person who is
not all there mentally, that is inept socially etc, or appears to be a bit thick. Struggles to fit into normal society, and
subsequently rejected and described to people as a bit slow.
May also be used lightheartedly if someone is perhaps day-dreaming and not paying
attention when asked a question. Similar to, but not quite the same"a few beers short of a six-pack", or "a few screws loose."
What if we asked Dudley if he knows?
What?
You're kidding me right? Theres no way he'd know. In fact stay away from that bloke
Why's that?
You know, The lights are on but nobody is home.
