The Molotov-cocktail was a finnish strategy of dealing with tanks during the Winter War in 1939-40.

Molotov was the foreign minister of the USSR and he apparently said that the russian bombers were dropping bread for the finnish people. To no ones surprise, they didnt drop bread, they dropped incendiary cluster bombs.

So the Finns started called bombs “Molotov bread baskets” and then returned the favor with their homemade cocktails.
