When a character wears his or her clothes with both or one of its sleeves pushed or pulled up. This can be either to cool themselves off, to prevent the sleeves from getting dirty or wet or getting in the way of what they are doing, or simply due to the characters' taste in fashion. They also do this if they are preparing to deliver a blow to someone in a comical way or if they are getting ready for something difficult.
Do not confuse with sleeves rolled up, in which cases the sleeves are carefully folded up the arm, not simply pushed up.
