I used to get that's what she said'd a lot. My boyfriend uses every opportunity he can to thats what she said me.
At one point last year my friends just resorted to saying it in reference to me.
Sometimes it is annoying but I find them pretty funny when they're used in proper contexts. Occasionally I but out a "that's what he said" or will have a friend or my boyfriend go to "that's what she said" it but then they think about it and go "Oh...I guess that's a he said."
