Input: Text: i'm new to reddit and just discovered tifu and am just delighted to to join in on this most wonderful gathering of fuck ups. i don't know how many of mine i will post on here (are there rules about this?) but i'll start with one from a few years ago. and i would just like to say, it's good to be here.

so! i had just started seeing someone i had been crushing on, hard, for years (i'm a girl, he's a guy btw) - so when my relentless flirting and generally being really cool paid off and we started sleeping together i was over the moon.
it got to the point where he would come strait to mine after work when he finished late (he worked as a barman while doing his degree) and just get into my bed... - the dream.
i had perfected the 'i've been snoozing' natural make up look, spread books around me i totally had not read etc etc. was generally still trying to impress 100% of the time.
one night he was coming over, i'd been waiting in bed trying not to count the minutes till his arrival. when i heard him knock at the door i leapt out of bed to my bedroom window, which is directly above the front door and flung it open to check it was his pretty little head waiting down below.
this is where the fuck up happens:
my room is dimly lit by one small bedside lamp, and on the 2 step journey from my bed to the window, out the corner of my eye i spied a pair of racey knickers among my clothes (i have to say here that i'm not a really tidy person with my clothes and sometimes clean laundry gets mixed in with discarded dirty stuff and creates a kind of roulette laundry mountain)  in a total loved-up adrenaline fueled dick head maneuver i decided to be silly and sexy and scooped them up en route, in one swift, ill judged, motion. as i popped my head out of the window i sung a breezy 'oh hiii' and briefly dangled the knickers, like a toy to a baby, aloft my head before releasing them from my fingertips and letting them flutter 'sexily' down onto his beautiful upturned face.          
i then went skipping down the stairs in my nightie to let him into my boudoir. i opened the door and he was standing there with a pale look on his face, holding my knickers out at arms length, and said very flatly, and matter of factly: 'i think you came on your period in these'
i snatched them out his hand and laughed, 'oh haha, oh no, surely not... really?! oh how embarrassing!', while simultaneously feeling a hot red flush quickly creeping up my neck, probably the same shade as the gusset of the knickers i had whimsically decided to drape across his face.
i just span around and ran up the stairs ahead of him, cheeks aflame, so i could ball them up and toss them in the bin, but it kind of killed the moment and blew my sexy siren cover to boot. i tortured myself further the next day by inspecting the offending article and it was as bad as could possibly be; total blood bath in crotch of pants.

TIFU by not doing my laundry!!!!! (NSFW)
