Sounds like you haven't done enough work that you aren't trained for around the house -- plumbing repair, electrical wiring, re-roofing, siding -- that sort of thing.
Any man will tell you, each of these jobs (especially ones assigned by his wife) comes ready-made with a set number of cuss words that must be spoken before the repair can be completed.
For example, replacing a bad shut-off valve on the water intake under your kitchen sink requires 11 cuss words before it can be completed successfully.
