"to cheat," 1583, from obsolete noun fobbe
"cheat, trickster" (1393), perhaps from O.Fr. forbe
"cheat." Alternative etymology holds that the word is perhaps related to Ger. foppen
"to jeer at, make a fool of" (see fop
); or from Ger. fuppen, einfuppen
"to pocket stealthily," which would connect it to fob (n.)
. To fob (someone) off
is first recorded 1597.
