Timewaster is someone who arranges to meet and doesn't show, with no explanation, normally with all means of communication turned off or unanswered.
Anything less than that can be a total nuisance, endowed with an over-abundance of the fuckwit factor and a frustratingly teeth-clenching irritant but, for me at least, until I have actually carved out time and space in my diary to meet someone it is not timewasting.
