- Both expressions mean to work extremely hard, to the point of physical or mental exhaustion.
- Work your fingers to the bone emphasizes relentless, often manual or detailed labor.
- Bust your hump is more colloquial/slangy, also implying strenuous effort, perhaps more physical exertion or just working extremely hard in general.
Explanation
Origin
- Work your fingers to the bone: A graphic, evocative idiom likely from the 19th century or earlier. It paints a picture of working so intensely, especially with one's hands (e.g., sewing, farming, writing), that the flesh wears away, leaving only bone. It symbolizes extreme, exhausting toil.
- Bust your hump: Likely American slang, mid-20th century. Hump can idiomatically refer to the back, so busting your hump suggests back-breaking labor. More generally, it came to mean exerting oneself to the maximum, working very hard on any task. Bust implies extreme effort or strain.
