But it was the follow-up responses that truly got the internet pumped.
Charlie went on to reveal how things went from bad to worse after she confronted her aunt, and also reveals how a cousin was less accepting than expected.
But Charlie appeared to take it all in her stride, even managing to make a joke of it.
Charlie also revealed how she wasn't going to go to her cousin's birthday as she was having "a big lesbian orgy that day."
But while a few criticised her choice of words, most users spoke out in favour of her actions.
It even sparked an Aunt Marie parody account.
