foot bail
n.— «A routine traffic stop for failure to use a turn signal in the 1200 block of Mabel Street at 10:41 p.m. Monday turned into something different when both occupants of the car decided to make “foot bail”—policespeak for beating the heat by shank’s mare. Unfortunately for them, there’s another piece of police lingo—”You can’t outrun the Motorola” (police radio).» —“Police Blotter” by Richard Brenneman Berkeley Daily Planet (California) Aug. 12, 2005.
