Cover art for Jellylegs lyrics by Children Collide

I think it's about liking a girl, but she is unresponsive to the boy's advances. 'blew holes in me with cold silence' It makes him nervous giving him jelly legs that stretch out like a rubber band.

Also the girl is in a sexual relationship with her grandfather. ...well I'm unsure about that part.
