The pelican is an act of oral sex performed on a man, where one's partner deep throats the entire penis while fitting the ball sack in their mouth as well. Thus mimicking a pelican fitting an entire fish in it's beak.
A variation of the shocker where only one finger goes in the vagina, but three go in the anus. The hand shape resembles that of a pelican with a large mouth.
