<human>: Could you distill the essence of the text into 1-3 sentences?

If you think you know embarrassment, you know nothing! And this particular embarrassment happened slap bang in the middle of college. 

This week the river is flowing red, except its more of a lagoon with some nasty shit thrown in there for good measure. I've sat uncomfortably through 2 hours of mechanics so I figured that I'd go to the loo and sort myself out etcetera. Once I'd finished, I foolishly stood up and Krakatoa erupted. Its exactly like squirting the dregs of the ketchup bottle on your chips and having a nasty red shart splatter your plate. Initially I thought the disaster had been avoided as I only noticed a drip on my thigh. I'm about to leave when I notice my shoes are sticking to the vinyl floor. In fact what I had failed to realise was that a tidal wave had swept across the back of my jeans, trickled down the trouser leg and settled itself in the back of a brand new pair of walking shoes. It looked like someone had slashed the femoral vein at the back of the foot and let it bleed out, all over a white floor. Cue footprints. There was no way I could go out of the cubicle at peak time covered in period blood and so I seized the opportunity when the coast was clear (and leaving a trail), exited the maths block and consequently had to walk through college, filled with other girls knowing exactly what had happened, to the nearest exit over the other side of the college as they are currently doing building work on the quick way out. Cue disgusted looks.
<bot>: Nasty red period shart all down jeans and shoes, left a trail to the prize in blood footprints (seriously looked like an exorcism had taken place) and had to walk through college filled with people in aforementioned apparel.
