Is when you bring, or are brought, chicken soup when you, or both parties, are sick. Only to completely fuck each other's brains out. Rarely, if ever, does anyone actually eat said soup.
Friend 1 - "Hey man I heard you were sick so I had my sister bring you some chicken soup. Did you like it?"
Friend 2 - "Oh! Yeah bro, it was absolutely fucking amazing! Best chicken soup party ever. I ate her all night!"
The beautiful residue left in a womans panty crotch after long wear and/or arousal. Usually drying to a powdery whitish/yellow color, holding in the scent of her sex as well as making for a great sniffing and licking prospect later while jerking off.
Hey, she was so hot before we banged, I slipped her pantys off and realized it had panty soup. I carefully rolled them up, crotch on the inside and pocketted them. Later they gave me a lot of pleasure, sniffing and licking the crotch while I jerked off on my towel.
