COKE - There have been various accounts of the etymology of this sign
and for why this sign is the same as the sign for COCAINE. Until 1929,
the formula for Coca-Cola called for an extract of the coca plant, the
sameplant from which cocaine is derived. Coca-Cola was originally
marketed as a tonic with medicinal effects. When the use of cocaine
became controversial, the formula was modified until all traces of the
drug were eventually removed. The Clerc Center at Gallaudet University
published a different account of the etymology of the sign in 2001.
This account suggests that, during World War II, individuals who donated
blood would receive a Coke after donating. On this account, the sign
for Coke is the same as the sign for a shot or injection.

also mean SWEET, although the more common form for "sweet" uses 4 fingers
instead of two.
