Video Example

This song functions as a modern illustration of cacoethes, an irresistible and often self-destructive compulsion toward something harmful.

The repeated lines “Make me an addict” and “Can’t say no to you” emphasize the loss of restraint characteristic of a cacoethes. The speaker is not merely expressing desire, but a recurring, self-aware return to what they know diminishes them (“I’m going dumber every time I answer you”). This reflects the historical sense of cacoethes as an ingrained, almost pathological inclination.

The drug metaphor (“I’m a junkie, you’re the drug,” “quick fix,” “entertainment sickness”) parallels the older medical usage of cacoethes, which referred to a malignant condition resistant to cure. Likewise, the relationship described in the song intensifies despite awareness of its harm.

Rather than simple attraction, the lyrics dramatize a cultivated appetite for ruin, a compulsive surrender that aligns closely with the moral and psychological weight of cacoethes.
