Learn English – Opposite of disciplined with positive or neutral connotations

The verb to table, when applied to parliamentary procedure, has opposite meanings in the US and UK.

From Wikipedia:

• In the United States, the motion to lay on the table (often simply "table")...is a proposal to suspend consideration of a pending motion.
• In the United Kingdom and the rest of the English-speaking world, a motion to place upon the table...is a proposal to begin consideration of a proposal.

With regards to the programming context mentioned elsewhere, you can use terms such as "absent" or "missing" as in:

Assert.Absent( ... )

Assert.Missing( ... )

These seem highly likely to confuse whoever needs to read your code next, however, since no one will be searching for these terms. Contains is an extremely well adopted term for checking containers for objects. NotContains (from one of your comments) will at least match a query for "Contains".

In short: The terms exist but I wouldn't use them.
