Born-Again Becca Bratt is the best example of "yeah-yeah-yeah-yeah-yeah". She does a scene in Back Seat Whatever, the ripoff of Bang Bus, just before she found Jebus, in which her whole patter breaks down into cadences of her catchphrase.

I always fast-forward girl-girl filler scenes, and that clip posted by pinupmutant is the reason. Girl-girl is a relic of the days when porn was mostly accessible as pictorials in "Penthouse".

"Oh, you like that!!"
"Yeah, I like that!!"
"You like that?"
"Yeah, I love that. That is so hot!!! Oh, yeah-yeah-yeah-yeah-yeah!!"
