Commonly used to define members of the Irish travelling community. The previous definition cites the use of 'tinker' in this context as ignorant. Maybe he/she is a tinker (in the metalwork sense of the word) and does not like his traditional profession to be used in such a manner. I would like to add that Irish travellers traditionally were very improvising metal workers and sold pots made of scrap metal to make a living (as opposed to topping trees badly and laying poor quality tarmacam like they do now).This is the long-standing origin of the association of Irish travellers with the word 'tinker'. They are tinkers. Hence the phrase, ' Any scrap copper there boss'.
There was war at that tinker's funeral in Balinasloe there last week- all the pubs and shops were closed for the week
Ploki is a word used for computer programming development testing. It has no meaning other than its significance as a word with no prior meaning. It therefore is easily found in a code search and thus finds its usefulness in spotting test code before it goes live for any developer who uses this word as their "testing word" while working. The word was picked for its prior meaninglessness, its unique order and combination of letters, and for the convenience of the approximity the letters have to one another on the standard English keyboard.
