What's the word for the sound when...

[Melonfish]

ptwang i'd say.

done that - stars was the word the came out, at least that is all I can type here. followed by me ducking as it rebounded off the brand new BMW (apparently a sizeable dent) and came straight back at me leaving me fearing I was going to get hit!

Best when followed by a tinny sounding bang as it hits a passing car.

twas no tinny sounding bang. more like a metallic thud and £££'s of damage. my OH then made the noise of a police car and calls me a fugative... (apparently I have gotten very good at hitting the most expensive car around - done this more than 4 times now in the last 2 years but only once has it come back at me and zipped under my wheels as I left the scene at speed...)

Given my general lack of nerve, and fear of any wheel-skipping, it would probably qualify as a 'pingf**kit!', although that is more commonly applied to small sprung components which make their escape...
