When a male suffering from "Blue Balls" satisfies his sexual needs with a smurf action figure, often resulting in blue genital warts, which, when popped, make a small cherp similar to the sound of a robin. It is said that such events happen often in the Pacific Islands on a regular basis, and that the Blue Robin is a sort of sexually transmitted pandemic there. The most notable case of the blue robin would be that of Jeromy Fischer, the original lead singer for british pop band "The Beatles". His case of Blue Robin was infamous, often ruining recording sessions with the rest of the band, and resulting in his expulsion from the band and inevitable death.
