A psuedo flasher is someone who wears their nasty flesh coloured panties out of necessity (it's laundry day, all their other underwear was burnt in a house fire, etc) and the fly on their jeans is wide open. Usually they don't realize this for hours. Upon realization, the psuedo flasher can a)see the hilarity of the situation or b)be completely humilated and move to a different city/country/planet. Ideally a pseudo flasher would feel mildly horrified but mostly pleased.
Cheryl: Man, I was walking around the park all day long, I didn't realize I was being a psuedo flasher until I got home last night.
Jane: It's a hard knock life.
