Like having wetness/arousal in a public place, at dinner at a restaurant, movie theater, working at your desk, waiting in line, in a waiting room, whatever public place....having arousal so much when seeing something, thinking about something or having some kind of sexual touch from someone or something....to where it makes you so wet, that your panties or pantyhose are soaked and you have to either go to the ladies room or your car, or lock yourself in your office and take them off and put them somewhere and go with out them, or change them because they are uncomfortable to wearing them, being so wet....from an especially strong arousal from whatever stimulation source.
Then if they are that wet you either wear them wet, or go commando, or change.
That must have been some trip to the movie theater, what happened at the movie theater? did they come off? :)
