Something about "cranky"
i was in a lift and overheard two people talk about their work.
A: Work the whole morning?
B: Yeah
A: So cranky, ha? ( or some word like this pronunciation)
i can guess the meaning, like "tired" or something. my question is: is this "cranky" often used this way? is it American english or UK english? can it be used just between friends or any other situation?
