Boorish is the term that accurately describes someone who is rude and lacking in refinement. The word originates from "boor," which refers to a country bumpkin or unrefined person. When someone behaves in a boorish manner, they exhibit a lack of social graces, often being insensitive or crude in their interactions with others.

The other terms listed have different meanings. Boisterous refers to someone who is noisy, energetic, or cheerful, often in a way that may be overwhelming or disruptive, but does not inherently imply rudeness or lack of refinement. Bourgeois relates to a social class that is characterized by materialistic values or conventional attitudes, often associated with middle-class society, but does not specifically denote rudeness or lack of sophistication. Catharsis is a psychological term referring to the process of releasing and thereby providing relief from strong or repressed emotions, and does not apply to social behavior or refinement.

Therefore, boorish is the most fitting term to describe someone who is both rude and lacking in social elegance.
