The kind of love described in Placebo's song Special K. You are so in love with another person, that it leaves you dazed, confused, unable to move. It's so chaotic, but you feel like no relief will ever come. But even though it's so hard, you never want it to die, you never want to crash or hit rock botom. Unescapable love.
Girl: Wow Jake I think I'm in Special K love with you.
Boy: Your love for me is like horse tranquilizers?
Girl: Well.. yes. I can't control myself.
