a pile Jack Rice couldn't jump over

old-fashioned A particularly large sum of money. A reference to a famous steeplechaser (a horse that jumps over obstacles in a race) by the name of Jack Rice. Primarily heard in Australia. He had been expecting a pile Jack Rice couldn't jump over, so his face fell when I told him he'd only won about $100. Whoa, a fancy car like that costs a pile Jack Rice couldn't jump over—she must be loaded. When I started investing in the stock market, I'd hoped to make a pile Jack Rice couldn't jump over, but that didn't exactly pan out.
