I can’t say I agree…for one, giggling has historically been a feminine trait (like the stereotypical airhead bimbos back in the day). Also, guys will usually curtail after a couple of good “ha-ha”'s, and rarely to almost anything. Can’t say that for girls.
Hot flashes?
I dunno - in my neighborhood it was a sign of weakness for guys to tee-hee.
It’s not really the same thing; that response is more of “I head you, but can’t believe what you said” kind of thing.
When my son is with his friends they sound like Beavis and Butthead. I think that’s the male equivalent of giggling. Their voices are lower so it sounds different.
You might also want to take geography and culture into consideration. One trait might be percieved as very common in one corner of the world, while completely alien in another. What is coded as masculine/feminine behaviour is very different depending on where you are. Giggling can mean different things depending on culture. Who does the giggling in a certain culture can depend on gender, age, social group and more. Et cetera. As with most human behaviours.
I’ll add that guys tend to giggle/chuckle/laugh because they think something is funny. I think the OP is asking about girls giggling about everything.
ETA: Ah, you are the OP. :smack: So I’m agreeing with you
