The title of Dev's "In My Trunk" is at least partly metaphorical. (Think "whatcha gonna do with all that junk." Then think of literally anything else.) In the video, it's literal. The inventory of Dev's trunk: people (dancing and/or bound-and-gagged), smoke, shooting sparks, other sorts of SFX, the north, east and west, that dump and herself. And yet it always appears empty! Strange! Also worth noting: the track's probably got one of the top three uses of "costly" in its lyrics, and if you disagree, please name three tracks better without doing a really specialized Google search.
