roll up one's sleeves and rub one's palms—be eager for a fight ❍ 但她一得到可以逞威的地位如校长之类，不就雇用了 “～”的打手似的男人，来威吓毫无武力的同性的学生们么？(鲁迅《华盖集》 46) But when a woman gets a position like that of a college president where she can exercise authority,she hires thugs who"roll up their sleeves"to intimidate helpless students of her own sex.
