Input: Text: this happen two days ago at work:

it was casual friday so i wore my favorite jeans, and since the only clean pair of underwear i had were worn out with a stretched elastic band that slides around my waste, i naturally went commando. 
i hadn't shat that morning as usual, buy all seemed well through the morning. now, usually i bring my lunch to work, but this day i decided to splurge and go to mcdonalds. after i eat, i am standing by my car in the company parking lot enjoying a cigarette when i feel a bubble deep in my gut... ok, i think, this feels like the perfect post mcd's fart to let rip in the parking lot before i go back to work, you know, get it out before i'm back in close cubical quarters...

but this one was different... it started out like the fart it was expecting, so i loosened up a bit... and then it just started dribbling out... it must have been built up from the night before, but it just came coming out at a slow dribble, and my intense clenching was all that was holding it back... i proceeded to dance around in the parking lot trying to grab my car keys from my pocket while vigorously clenching my butthole in my now heavily soiled favorite jeans. ( keep in mind i'm commando.) 

i scramble into my car where i grab my mcdonalds bag from lunch and proceed to fill it with my own version of a big mac...not knowing what to do with it, i wrapped the bag in my ruined jeans, and took off for home... so with no pants on, and smelling like i shit myself, while driving with a toxic bundle to prove i did, i was okay being late back from lunch. 

i go home to shower, throw on some clean clothes, and i head straight back. no sweat. nobody would notice if i was a little late back from lunch... and maybe nobody will notice my different colored jeans. 
so i show back up to work, about 45 minutes late, to find a group of coworkers standing in the doorway about to go on their lunch breaks, and they are having a conversation about if i had actually shit my pants or not... i guess someone had pointed me out through the office window and they all saw me dance around and hop in my car and drive off...
and i even had one coworker point out in front of everyone that i had different pants on...

 

edit: i didn't even use a throwaway... this actually happened...

TIFU: TIFU by going commando.
