Needs a boom-box .. hmm ..
Lets call it the 'iScream' it would be a bluetooth device, running on rechargeable batteries with enough power for, say 2 hours, of 100db (or more) noise, though the iScream could be made even more useful with the addition of a few buttons as well as the GPS...
'I'm in the boot(trunk *) of this car '
'No No I don't want to be hit/ raped/ converted to another religion'
Hmm i wonder if it could be built into a chastity belt? - the iChaste?
Ok, that's enough I think, I'll get my loud coat.
