you know that time when you pull down your pants and you feel a flossing sensation between your cheeks... it's only when you see that your thong is a v with a hanging string that you realize the string detached from the waist band and flossed you clean on the way down....surprise!
i thought i just had a severe wedgie til i realized i got surprise flossed

i stared at my thong confused and in disbelief thinking i must have gotten one that was 10 sizes too big until it occurred to me that i got surprise flossed

my friend told me about her surprise floss job, and i laughed so hard i farted - true story.
