Rudeness

Rudeness (also called effrontery) is a display of actual or perceived disrespect by not complying with the social norms or etiquette expected within a relationship, social group, or culture. Social norms are established as the essential guidelines of normally accepted behavior within a given context, and individuals often establish personal boundaries to meet their own needs and desires within smaller settings, such as friendships. To be unwilling to align one's behavior with these norms known to the general population of what is socially acceptable is to be rude. These norms may resemble a sort of "unspoken law", with social repercussions or rewards for violators or advocates, respectively.

Rudeness, "constituted by deviation from whatever counts as politic in a given social context, is inherently confrontational and disruptive to social equilibrium". Forms of rudeness include behaving in ways that are inconsiderate, insensitive, deliberately offensive, impolite, obscene, or that violate taboos. In some cases, an act of rudeness can go so far as to be a crime (e.g., the crime of hate speech). In many cultures, joking can create a context where rudeness is temporarily excused or indulged for the purpose of making people laugh.

The concept of rudeness is somewhat subjective (i.e., different people may have different views) and contextual (i.e., it depends on the setting). Some actions, such as wearing shoes indoors, using vulgar language, wearing headphones, or addressing elders by their first name, may be deemed rude in one setting and perfectly acceptable or even expected in others.
