Lyric discussion by leadvocals 

Cover art for Riptide lyrics by Vance Joy

I thought about the meaning , and the biggest theme in this song is change. The song can be interpreted as a awkward guy , who gets a beautiful girl that all this friends are jealous of , However the girl has a dark side and always does things wrong. But even after everything the guy still loves her. Further the guy is witnessing his girl change and become darker , she is literally changing like a were- wolf, (wolf is even in the lyrics of video and also the "woooooooo" and they come unstuck - sounds like a wolf's cry.

Vancy joy - said himself he was experimenting with sounds and images when he came up with this song. Anyway just my thoughts on it anyway.

My Interpretation

@leadvocals Wolf is in the lyrics of the video, not for a reason. The line is "Your'e gonna sing the words wrong" but the video is just showing that the words are wrong because thats the lyric so they put in "Your'e gonna sank the world's wolf" to show that indeed, the lyrics are being sang wrong.
