I recently read
"looks like he's a few cans short of a six pack"
Can somebody explain it?
It' like "le falta un hervor"? (it's not enough cooked)
We use this term when a person who is not relly dumb (he can read, talk, and mainatin a conversation) but it's no really clever (you have to explain all, "esasily foolable", and so on)
