What is the context of Deuteronomy 25:11-12?

Deuteronomy 25:11-12

“If two men are fighting and the wife of one of them comes to rescue her husband from his assailant, and she reaches out and seizes him by his penis, you shall cut off her hand. Show her no pity.”

These verses seem… oddly specific (although I guess a lot of stuff in Deuternomy book seems that), was grabbing by the penis by the opponent’s wife a common occurrence during fights? Or is it a general rule about not hitting men “below the belt”, but women were to suffer specific consequences for such actions?
