@marcsman: True story:
[spoilers because this is probably extremely gross! You've been warned. Stop eating. I hope this isn't mod-worthy; sorry if it is; it is basically the Something About Mary situation for women]
When I was in junior high, I lined up near the door because the bell was about to ring. I finished my assignment early, so it was only me and this outcast girl at the door; everyone else was still absorbed in their assignments. I was a good ten feet away from her, and I think she thought I wasn't paying attention, so she... umm... reached "down" into her pants, then brought her hand up to her scalp to slick back her hair... or something. I don't really know exactly what she was doing... I didn't ask. Maybe she was attempting to smell herself, but then thought someone was paying attention and pretended to be fixing her hair instead.
Thanks for the story T_T
