A numeric symbol referring to Adolf Hitler’s birthday on April 20. In some cases, it is also used in reference to the birthday of Maurice Duplessis, the socially conservative Premier of Québec from 1936 to 1939 and from 1944 to 1959. In either case, use of this symbol is often tongue-in-cheek, as it also happens to be an important symbol in cannabis culture. As such, most uses of the symbol are not hateful, and context is highly important in understanding its meaning.
