Cover art for Limp lyrics by Fiona Apple

this song physically makes me shake because of how badly i can relate to the lyrics and fiona's voice. amazing.

the meaning is rather obvious: she's in a conflicted relationship/friendship with someone who she once thought wanted to help her but is only getting high off of putting her down and dragging her back up. it takes a special kind of sadistic to be this sort of person and she's describing what a broken, shallow, hollow and ultimately cowardly (you'll be lying limp in your own hands - he still has to get off using her unconsented emotional pain, maybe physical? pain) person he is. i'm assuming 'he' from the metaphor.
