Shocker (hand gesture)
The shocker, also known colloquially as "two in the pink, one in the stink," is a hand gesture with a sexual connotation. The ring finger and thumb are curled or bent down while the other fingers are extended. The index and middle fingers are kept together (touching) and the back of the hand faces outwards (away from the gesturer). The gesture refers to the act of inserting the index and middle fingers into a vagina and the little finger into the receiver's anus, hence the "shock".
