What is Burning Love?

Still thinking about Stone in Love. Particularly, "Burnin love comes once in a lifetime". What is burning love?
My understanding was that if you got "burnin love", it stayed with you forever, not just once in a lifetime. Symptoms were treatable with medication which helped sooth the "burnin", but there was no getting rid of the "love".
Also, do you catch the "burnin love" from the Blue Jean Girl? (no offense intended to BJG, just wonderin').
