Baby boy or girl meaner?

For mamas who have both boys and girls, who made you meaner? With my boy I wasn't mean, I was relatively calm but this pregnancy im not sure what I'm having yet but everyone I know thats had girls has said they were mean and mad as hell during their pregnancies AND gained weight super fast which I am too. It's like I'm constantly irritated and it takes little to nothing to make me either snap or cry and I just wasn't like this with my son.
