Come hither

[Mark Zuckerberg]

This technique is a form of [fingering] a womans [vagina]. A man or woman must make the boy scout sign with their index and middle finger, and then insert these fingers into another womans [vagina], palm up. As the the fingerer withdraws the fingers, they must curl them up, as if you were beckoning to someone to come hither, rubbing the [G spot]. When combined with [oral sex] techniques, namely licking of the [clitoris], this can be very stimulating.

[Dave Paprocki]

the act of sticking your index finger up a female/males bottom and bending your finger in the motion of calling somebody over.
