The act of a man putting his penis between his legs to create the mangina. Except for extreme cases, tuckering is absolutely prohibited on a normal basis. Tuckering is usually only permitted in times of dire need, such as when a butch or sheman is coming on to you in a bar/club.
Buffalo Bill enjoyed tuckering his penis in "The Silence of the Lambs."
