nullo

A bid in which the bidder asserts that he or she will not take any tricks.

If the adversaries of a nullo revoke, the declarer can give them three of his tricks, or take 100 in honours as penalty. If he revokes, they take 100 penalty as usual. SUGGESTIONS FOR BIDDING. The dealer should never bid a nullo originally ...

It takes a better nullo hand to raise nullos than to bid them. Dummy shows. A player who has once been called off from nullos by his partner should never return to them.

One who has their genitals (and sometimes nipples) surgically removed (nullification) as a form of body modification.

This public presentation of the mutilation of the penis is not obviously very different from the forms of disassembly of the penis engaged in by male body modifiers – particularly nullos and transgenders – on the Body Modification Ezine website.
