In this week's new video Mama arbeitet wieder, a construction company boss tells his foreman:
Aber bevor wir hier abziehen, lassen wir's noch mal richtig krachen [umgangssprachlich], was?
But before we pull out here, we'll make a really big noise [slang, celebrate], right?Play Caption
The verb krachen is defined by the Duden dictionary as primarily "einen Krach verursachen, auslösen" or "causing a loud noise." Its slang meanings are "to have a fight with somebody" (Krach haben) or "to suffer a bankruptcy" (Krach erleiden), the latter similar to the "crash" of the stock market in English. The verb combination krachen lassen, however, usually means "to celebrate."
Da wünsch ich euch viel Spaß! Lasst es krachen [Umgangssprache]!
Then I hope you have a lot of fun! Make some noise [celebrate]!Play Caption
A variation to the translation "to celebrate" is made in the case where a car really "makes some noise":
Und die lassen es in der brandneuen, über zweihundert PS starken A-Klasse so richtig krachen.
And they'll really, in the brand new over two hundred horsepower strong A-Class, make some noise [idiom: "cut loose"].Play Caption
So the slang term "krachen lassen" is usually used in connection with some kind of celebration, such as a birthday party or New Year's celebration. 2016 is still some months away, but that gives you a chance to get some practice celebrations going in the meantime. Lass es krachen!
