Why is there sack tapping?

Sack tapping, or the act of striking someone in the groin, is often seen as a prank or a way to assert dominance among peers, particularly in male social groups. It can be a misguided attempt at humor, reflecting a culture of playfully testing boundaries or engaging in roughhousing. However, it can also lead to physical pain and emotional discomfort, and many people find it inappropriate or disrespectful. Overall, while some see it as a form of bonding or joking, it's important to consider the potential consequences and the feelings of others involved.
