Orphaned body part

When someone shares pictures that are a close-up or cropped to only show one body part. It is commonly done with genitalia and feet, but can be done with any body part. This could be done for different reasons.

For example men may do this by sharing pics of their penises and women by sharing pics of their feet to be sexual.

People who are obese will share these pictures to focus on the one part of their body they are comfortable with or feel is the most attractive.
