Input: Text: this happened years ago. i'm a dude, married, and my best friend is female. yes my wife is okay with this! the bff is bi, which i would sometimes forget because she normally dated dudes (back when she was single).  

this fuckup isn't that bad, as far as fuckups go. it's just a little cringeworthy and i think it's funny.  

anyway. my wife and i were having a big party at our house one night. our closest friends were there, and some of their friends who we'd never met before. everyone was having a great time (and no the party did not go horribly wrong).  

at one point during the party, my bff was chatting with a cute lesbian chick in the kitchen. in retrospect, they were very obviously interested in each other but i didn't notice it in my drunken heteronormative stupor. i honestly thought they were just talking. what i *did* notice, however, was that my bff's chest was bright red, so i pointed it out to her.  
she looked a little annoyed at the interruption and tried to dismiss me by saying "oh, it's nothing" or something like that.  
but when i've had a few drinks and i'm feeling *extra helpful*, i don't get the hint very easily.  
so i pressed the issue.  
"no, really, your chest is like bright red!"  
she tried her best to subtly get me to drop it by saying "oh, that just happens when i'm drunk." and then she tried to go back to talking to the cute girl.  
and ever the smooth wingman, i reply with "no, man, i've drank with you like a billion times and i've *never* seen that happen!"  
now her face was getting red too! she spoke through her teeth this time "it just means i'm a little.. *excited*, okay?"  

the realization hit me and i *very smoothly*^^/s said something like "i see what you're getting at" and winked then walked away.  
both girls facepalmed pretty hard and that was it.  
it wasn't until the next day i found out that they had been flirting pretty hard and i had completely bumbled through and ruined the moment. she still teases me about it to this day!  
  
edit: automod says i have to include a

TIFU by trying to be helpful and completely ruining the moment.
