Acronym for "I Want You So Bad". Ironically used by partners who claim they want to be "yours for eternity" and beg you not to leave them, only to disappear (ghost) for days without a word. A mix of intense affection and confusing silence.
He: "Touch me, steer me, IWYSB. Don't leave me alone."
She: "You said "I Want you So Bad" but you've been gone for days. How can I steer you if I don't even know if you're okay? I'm worried sick but you don't care...
Eternity feels very short when you disappear for days.
I love you so bad. I love you so much it hurts. Can be used when talking about someone you're with and love a lot, but is typically used for crushes, hence the hurting.
