a few french fries short of a happy meal

Mental; not quite all there. Acting mental. Not thinkin' before acting. Weirdo. Doing stupid shit that makes no sense...like without thinking. Not acting very bright. Meant not as a compliment but as a wake up and start thinking with your brain type of comment.

I dunno what to tell you man. That boy is a few french fries short of a happy meal..that's fo' sure!

One Short of A Six Pack

A term used to describe a person who is not all there. A person missing a marble or two - a few percentages off from being full blown retarded.

"I can't believe that guy just walked into that glass door - what is he...one short of a six pack?"

Few apples short of a fruitcake

A snowclone to express that someone is either stupid or crazy. The standard format is "a few X short of (a) Y", the idea being that Y is something that, with a few X missing, is not so good, and in the case of a person being compared to such, that something is "missing" in their thought process.
This one in particular has the appeal that fruitcakes involve nuts, thus further solidifying the point that the person is nuts themselves.

Did you see how Bob just flipped out over nothing. Is he having some sort of psychotic break?
Yeah, he seems to be a few apples short of a fruitcake. Might be best to keep our distance.

a few tacos short of a combo platter

someone who is mentally not with it...looney, lacking intelligence or just plain crazy.

yeah, you could say Jane was not the brightest bulb in the box, her elevator didn't go to the top floor, she is a few tacos short of a combo platter.
