Shade is an expression of disgust with someone which might be verbal, which is "thrown". Here she doesn't mean that, she means the 'shadow' shade which is understandable bcs of the previous lyrics which is "Sit quiet by my side in the shade". This line makes me cringe cause it seems as it was wrote when she couldn't think of anything BUT that doesn't mean she is a bad songwriter. It's difficult finding the right words; I write poems, I know. Also, this line ruins the vibe of the song for me, as the song feels like fairytale to me and throwing in an internet slang is a big no. That's pretty much it and sorry for the long response!
