The Chainsmokers: Waterbed
Listen, everyone should NOT take the song's chorus literally. Unless you can do a solid handstand against a wall for like 20 secs (on your own) you are to shake your fingers like a waterbed, or just clap. And by clap, I mean your hands. In any case, it's dangerous anyway, just like new music from The Chainsmokers. Have you either seen them live or at least footage? Mother fuckers can shake a crowd like a water bed, and you'll witness monumental jumps on stages, into crowds and anywhere there's a platform so stay alert.
