When something is at full blast, no half measures. Used across South America for work, music at max volume, or when someone is completely absorbed in something. It borrows the English word "full" and adds a Spanish twist, making it feel more intense than just saying "busy."

To sexually arouse someone or provoke intense physical attraction without necessarily going further. In Mexico and Colombia, calentar someone is playing with fire — lighting the fuse without being sure you wanna set off the firework.

To wait in a line of people to be served — the most hated yet completely unavoidable activity of life in society. Standing in line at a bank or supermarket can test a saint's patience.

An affectionate contraction of "mi hijo" (my son) used by moms, grandmas, and even complete strangers to address someone warmly. You don't need to be anyone's actual child to be called mijo. The taco lady, the bus driver, your neighbor, they'll all call you mijo and it'll feel like a warm hug.
