the.com/bootlegging

means The illegal manufacture, transport, or sale of goods, especially alcohol, in defiance of a law prohibiting them.

from From 'boot leg' — literally the tall shaft of a boot, which smugglers and sneaky drinkers used as a hiding place to slip a flask of illicit liquor past watchful eyes. The term was already in use for concealed contraband in the 1800s, but it exploded into everyday vocabulary during Prohibition in the U.S., when hiding spirits suddenly became a national pastime.
