Shit, that shit is why I never watched it. Looked like shit.
But there are scientific studies. See, for example, Corpus Applications in Applied Linguistics (Hyland, Huat, Hanford: 2012), where, in chapter 7 (“Corpora and Gender Studies”), Baker notes that, in the British National Corpus, women say the word shit more than men.
Still, you’re the moderator.
In fact, here are the first random KWIC (keyword in context) hits from the BNC:

I don’t know, MrQwertyasd, that looks like a lot of shit to me. Are you sure you don’t want to reconsider the premise of your OP?
Why would using the word ‘shit’ be a sign of being an ignoramus? I love to criticize Americans as much as anybody, but claiming British superiority on this point is dead wrong.
Honestly, my perception of the average English person is that their vocabulary is about nine words long, and four of them are “right” and two are “yeah.”
Well, some of us just say it so well!
Yeah, I think “fucking” is the real placeholder word here in the US (if not elsewhere). Some people seem capable of using it as their every third word.
Meh, Baker wouldn’t know crap from corpora.
The scene where they communicate in only fucks would be a good counter, though it’s more NSFW than I remember.
I always wanted to know why bullshit and horseshit meant a falsehood. Does the degree of fraud increase with larger mammals? Is whale shit even worse?
And what about motherfucker? What does that mean, exactly? The person fucks their own mother, or they go around fucking other peoples’ mothers? Or is it a smorgasbord of indiscriminate mother fucking? Fatherfucker just doesn’t have the same ring either, does it?
I forget which comedian pointed out that another word for motherfucker is father.
That just gets you sent to the Group W bench…
Who gives a shit why?
Don’t forget about unclefucker! Very NSFW, Southpark
I warned you! https://www.youtube.com/watch?v=uDDJvC2CGaU
Yeah, right…
Like our independence, it was just a very popular movement over here. 
Out of curiosity, I googled “shit” and got 396 million hits. “Fuck” garners 554 million.
Or milkman.
In related news, there is a leather goods manufacturer in Detroit called Shinola.
People in general swear too much these days, not just Americans. I especially despise the word fuck.
