**Core Concept**
Fetishism is a type of paraphilia characterized by an abnormal or excessive focus on non-living objects or specific body parts for sexual arousal. This phenomenon is rooted in the realm of abnormal psychology and is often associated with various psychiatric disorders.

**Why the Correct Answer is Right**
