Nee-naw

If it had not been preceded by the nee-naw of fire engines it meant that no warning had been given. There would be casualties.

Whenever an opponent went down, be it genuine or feigned, the West Ham faithful would simultaneously cry 'Nee-naw, nee-naw, nee-naw, nee-naw', mimicking the sound of an ambulance.

Tom is in rapt communion with his police car, lying on his stomach, pushing it round and round, making nee-naw noises.
