bet one’s bottom dollar. To be so sure about something that one will bet all one has on it, the last of one’s money, as in “I’ll bet my bottom dollar on it.” Commonly heard throughout the U.S. today, the expression comes from the American West over a century and a half ago, when poker was often played with sil- ver dollars. Someone completely sure of a hand would push his whole stack of silver dollars, including the one on the bottom, into the pot to cover a bet or a final raise. |
