cheaper/easier than inventing new swear words.
But where is the creativity in that?
I myself, over many years working on cars, boats and machinery, have amassed quite a back catalog in , obscenities, profanities, blasphemies, damnations, taunts, oaths, curses, insults, threats and abuses.
All used in to varying effect on recalcitrant components, in fact about the only things I haven't tried in motivating stubborn parts is expose by bumhole at 'em or waggle my willie in their direction.............Hmmmmmmn! There's a thought, I wonder if that"ll work!
