When your friend's sister's church minister tries to be cool by dropping a "That's what she said" into after-church-small-talk but messes it up ever so slightly and it comes out as "she said that". Your friend then recounts that story to their brother's brazillian girlfriend who thinks that "she said that" is the real saying, and continues to use it throughout a night of partying.

Similar but often mistaken for That's what she said, she said that is when someone says something that sounds inappropriate, intending for it to sound inappropriate.
Girl 1 is eating a cream puff when Girl 2 comes and sits next to her.

Girl 2: Is that good?

Girl 1: Yes. It's hard, but inside its creamy. Hehehe.

Girl 2: That's what she said.

Girl 1: You dipshit, that's a she said that.

The best joke ever created, popularized by the NBC show “The Office”. Famously said a lot by the character Michael Scott.
Dwight: I can’t believe you came.
Michael: That’s what she said.

"I think we can fit that in with the rest of them."
"That's what she said."

"Make sure it's long enough."
"That's what she said!"

"It hurts a little but it's not too bad."
"THAT'S WHAT SHE SAID!!"

"John, we're concerned about your drinking."
"THAT'S WHAT SHE SAID.... Oh."

what she wouldn't say.

unlike the common "that's what she said jokes", that's not what she said can be used when describing an act that she wouldn't do or something she wouldn't like. a reverse innuendo. because a normal audience is thrown off by this, it often results in a more uncomfortable situation.
m: we should bring back the "that's not what she said"

k: I am sure it won't be hard.
(that's not what she said)

m: Yeah, I know, but sometimes you're just not in the mood to do something that hard.

(That is not what she said)

k: This exchange could go on for ages. We need to stop.
(That is not what she said)

m: good call. it is never a good idea to stay up all night doing it.
(that is not what she said)

she said that: similar to that's what she said, but better. it's shorter and sweeter.
Two friends stand looking at the Empire State Building.
Friend A: "It's so big!"
Friend B: "She said that."

Two friends go out for burgers.
Friend A: "I can't fit the whole thing in my mouth."
Friend B: "She said that."

Friend B always wins.

a phrase used to turn a simple comment into a sexual joke
simple: "its so hard!" .. "that's what she said"
more complex: "every time i pull it out i almost break my back" .. "that's what she said"
