What was the worst "why the f*** did I say that" moment?

A little backstory: my grandpa got divorced and remarried, and with the new wife came a new daughter (in addition to the other 2). This Aunt (wall say Mary) of mine was notorious for sending me bad/low effort gifts, most notably one year for Christmas I got a burned cd of the same cd my sister received.

Anyway I'm at my grandparents house and I forget how it happened but they were talking about something like cheap things, and I go "What, like Aunt Mary's gifts?" thinking they were in the family too, they probably get it. Well they didn't laugh, they probably just didn't get it, so I say "You know, because she always buys cheap gifts". Still nothing, weird, and at this point I feel my sister start to kick me under the table, RUDE, I shot her an inquisitive glance before I believe saying something else about how my aunt bought cheap shit for us.

That's all I actually remember, I like to think my mom or dad actually told me to shut up, but that's all conjecture :/ I was for sure the black sheep of the family for a minute after that.
