Jolly Roger Salute means in slang: The Jolly Roger salute is a close cousin to the star-spangled banner. It’s performed mostly when an inebriated man gives it to a doggy girl. A friend comes out of the closet to tie a Jolly Roger flag round his neck. He begins to sing “Yoh yoh a pirates’ life for me”. It’s a wonderful move. (in Slang Dictionary, added by Onanism)
