When I was younger I had no filter, eventually I was slapped enough to keep my mouth shut. One time I was at my moms office and her boss passed, "Mom, is that the dragon woman with the lazy eye?" I may have gotten beat for that one. When I was in college I remember I was drunk and was talking to this one guy. He said something about this one chick I knew and was boasting about the sex and such. I just replied. "Yeah, what guy hasn't fucked her that way?" He was actually hurt and didn't know that she was a bit of a easy gal. Pretty much scared him off from seeing her again.
