In our Reserve if you "fool" around on your wife or partner, you are in trouble.
You will suffer the consequences and deservedly so.
One night a bingo a woman scorned, walked in to the crowded hall and threw some shitty underwear on the table where another woman sat. The scorned woman said "You want to take my man? Well you take his shitty shorts and you wash them."
Another fellow had his car windows smashed up. All of his lights were busted out. The woman went crazy on the car. She went back into the house, got his clothes and cut them up. She was berserk. She was like dancing around. The neighbors just watched as it played out. They had seen this before. The couple re-engaged many times even wanting to get married. They finally went their separate ways.
Yep, you want to fool around on an Indian woman, you take your chances.
Never heard of anyone getting sliced though. The attacks usually are on the clothes or on the man's pride.
Some women are pretty nice about it, they will just throw his clothes all over the yard. The really really nice wants will actually put the clothes in a garbage bag out in the yard.
Of course these same women almost always take their man back. :D
