Input: Text: okay, so this happened a fair while ago, but i've only just discovered this sub, plus the story still sticks with me to this day.

so, my older sister had just gotten engaged to this really cool survivalist-type guy, so the family celebrated by going on a camping trip, around the fire on the first night my sister's fiance decided telling some jokes would be fun, we all took turns, and as it came to mine i decided i'd tell a pretty racist joke cause i wanted to impress the fiance.
(not going to repeat for fear of insulting people)
as it turns out, the race of the fiance was the same as the race i was joking about, and it was an extremely insulting joke, after a few shocked faces and awkward seconds later, my sister said updated me on the facts, and the guy got up and left the camp entirely along with my sister.
come next week and we get an announcement from my sister that the engagement was canceled due to the fiance despising racists and hating myself and my family.

 

edit: just some things to clarify;
         - we later found out that he was already having difficulties with my family, and that just pushed him over
           the edge.
         - the guy was from new zealand, but his complexion didn't make it obvious at all, albeit i probably should
           have gotten a hint from his accent.
         - lastly, i don't remember it entirely, but it was a pretty common one about them screwing their sheep, it
           also had something to do with his mother too. if you guys really want it i'll try to google it to see if it
           comes up.

TIFU by being a racist little shit.
