piker Look up piker at Dictionary.com
"miserly person," 1872, formerly "poor migrant to California" (1860), earlier pike (1854), perhaps originally "vagrant who wanders the pike (1)" (which is the notion in Sussex dial. piker "vagrant, tramp, gypsy," 1838), but Barnhart and others say the Amer.Eng. word ultimately is a reference to people from Pike County, Missouri.
