That's a pretty interesting definition of joke you have there. Who exactly found this funny? Here's a quick test: if you're the only one laughing at a "joke" on someone, then it's probably not funny and you're just being a douchebag.

you're a bitch. FHL not yours.

:( poor girl.

bitchy. what the hell did you do that for? it's her fml not yours

just cause you can't get a guy doesn't mean you have to ruin your sisters happiness you bish

I actually had a girl tell that to me before when I told her I fancied her sister. She told me that her sister was a serial cheater and that she slept with a lot of guys in college and had an STD before because of that. I think that she was actually trying to ward me off from her sister because she knew her sister wasn't interested in me, whether she had a BF or not. Somehow, I wonder if it's the same girl in this FML. Isah, is that you? (Last name redacted for privacy!)

you did the right thing .

bitch..

Sibling jealousy? Even so, you are the worst sibling one can have. Did you not even think of her reputation?

You're a total bitch. I hope your sister finds out that the 'person' was u.
