Have a drink
The Spanish phrase 'tomar algo' directly translates to 'take something' in English. However, it's a colloquial phrase often used in the context of socializing and it's more accurately translated as 'have a drink'. So, if someone asks you if you want to 'tomar algo', they're not necessarily asking if you want to take something, they're likely asking if you want to go out and have a drink or snack.
