All the reasons the person who answered just above me is correct. I think there is another reason. TV and movies love to use the groin kick for cheap laughs, I think girls are curious as to how the boy would react.
when hormones kick in and they start to like the girls on tv in bakinis
girls don't have nuts
The only reason you should kick a guy's nuts is if he is attacking you and you need a way to get away.
I'd say a knee
Yes well only tomboys
kick him right in the nuts
kick it in the nuts
drop kick murphys, boys like girls, etc.
yes, it was very common for the indians to kick eachother right in the nuts.
I'm a girl and I actually do not like hitting boys, but I know many girls who do. I think its a form of confidence, show a guy that your not afraid to hit someone, that you can fend for yourself. Other times it can be a form of affection; like if she playfully punches your shoulder, she may be in to you. Thought I have seen where a girl would randomly punch a guy or slap him, maybe even kick is nuts, and I honestly don't get why, maybe she's angry, or some girls see that as flirting, all girls are different.
