There is no such thing as a "male huffer", not even in an Angus cow or anywhere else. Unless you were trying to spell out "heifer", the question has no merit thus cannot be answered.
However, even if you were asking how to identify a "male heifer" in angus cattle (which I assume you were more likely trying to ask), there still is no such thing as a male heifer. A heifer is only female, never either male or female. Heifers are immature female bovines, or female bovines that have never given birth to a calf. Heifers are often smaller and much younger-looking than an adult Angus cow. They do not have an udder like a cow does.

Angus is not any part of a cow. Angus is a BREED of "cow" or bovine, specified by the colouration and genetics that determine whether an Angus cow is purebred or not. Angus cattle are always all black, unlike other breeds that have followed the black trend like Simmental, Gelbvieh, Maine Anjou, Charolais, Limousin and Salers who, traditionally are not black.
