helmets and gloves
n.pl.— «Medical experts are ringing alarm bells over a so-called rite of passage for adolescents, played out in hockey and lacrosse locker rooms across North America, known as “locker boxing.” The battles, also known as a “cage match” or “helmets and gloves” are generally held after a game, with teammates sitting around cheering on the combatants.» —“Experts raise alarm bells over ‘locker boxing’” CTV.ca (Canada ) May 12, 2006.
