döppelfagger 

A person, who formally being homosexual, converts back to heterosexuality, but then is lured back to the other side, once more becoming homosexual.

"It's such a damn shame... we got him back onto the straight and narrow, but he had to attend that swinger party the other night. Some fella applied some pressure, and once again, he's licking the other side of the stamp"

"Crikey... a real case of being a döppelfagger"
