Okinawa Sweet Potato
The act of wrapping a rubber band tightly around a womans clittoris. Once it turs purple, it is ripe for the feasting. Can be eaten with the rubber band in place or with the rubber band removed. Often enjoyed by men and women alike. A variation of the Okinawa Sweet Potato is the Purple Cabage.
Guy says to his guy friend: Last night I was giving my girlfriend an Okinawa Sweet Potato and left the rubber band on way too long. I ended up just hittin the Purple Cabage.
