The brutal physical misery after a night of overdoing it with alcohol: headache, nausea, and regret. It's universal across the Spanish-speaking world and always comes with the promise to never drink again.

To harshly reject someone, to tell them to get lost without any courtesy. In Spain you use this when someone annoys you so much they don't even deserve a polite explanation.

A perfect deal where everything goes right and you profit handsomely with minimal risk or effort. It's the kind of business transaction everyone dreams of but rarely achieves.

A sandwich on baguette bread in Spain — the quintessential quick Spanish lunch you can eat with one hand. Made with ham, tortilla, calamari, or whatever you've got in the fridge.
