The phrase is based on the Brazilian version of homemade strong coffee, called "cafezinho." Wherever you go in Brazil, the minute you walk in the door, someone will pop the question "você toma um cafezinho?" (do you want a cafezinho?) and they won't take no for an answer.
Here is a recipe for making the Brazilian coffee standard: For each cup of water, use a heaping Tbsp of good coffee ground for espresso. The recipe also calls for sugar to taste. Add the water to the pan, add the sugar and dissolve well. Bring to boil over medium heat. When the water and sugar mixture boils, add the coffee powder, stir well and pour through a traditional cloth coffee strainer (or a paper filter). Pour immediately into a tiny cup. Adding a little hot milk makes a cafezinho con leite (little coffee with milk)
