To hold
the bridge of ones nose between the thumb and index finger, with the other
three fingers spread, whilst bending to 'grind' against somebody or the air on a nightclub
dancefloor, in disgust. A side-to-side rocking motion may be adopted simultaneously with the 'grind'.
You may
adopt the
nosegrind if an 'undesirable' attempts to dance with you. Always done best with a
fellow nose-grinder.
