When someone is said to "need a cheeseburger" it means that the person is way too thin - so much so that the person doesn't look attractive. The implication is that the person is anorexic / dieting too much and needs to put on some weight. Almost always said about a female but a male isn't immune.
"Damn, did you see how skinny Angelina Jolie looked at the Academy Awards the other night? That girl needs a cheeseburger!"
"LeAnn Rimes looks anorexic. Someone please give her a cheeseburger!"
Loser. Someone who is totally worthless.
"Maybe we should chug on over to mamby pamby land where maybe we can find some self confidence for you, you jack wagon!" (Geico commercial asking does a former drill sergeant make a good therapist?)
