No holds barred means that no regulations, rules or restrictions will be applied to a situation or conflict. A contest or dispute that is designated no holds barred is a contest or dispute where nothing is off-limits, it is a free-for-all during which any tactic may be fairly employed. The idiom no holds barred comes from the sport of wrestling, in which various holds are employed to pin one’s opponent. Eventually, certain holds were deemed dangerous to the participants and were banned from the sport of wrestling. Bouts in which the wrestlers did not follow the rules of the regulated sport of wrestling were advertised as no holds barred, the earliest print reference found in Manitoba in 1892. When the term no holds barred is used as an adjective before a noun, then it is hyphenated as no-holds-barred.
