'Der Gag' in German only means 'joke' or 'punchline'. The English verb 'to gag' (to choke, to muzzle) has a completely different meaning that the German noun does not have.
Sein letzter Gag war der beste des ganzen Abends.
His last gag was the best of the whole evening.
'Gag' is a word from English that is very common in colloquial German. It is used especially in the areas of comedy, entertainment, and marketing.
Die Show war voller lustiger Gags und das Publikum hat viel gelacht.
The show was full of funny gags, and the audience laughed a lot.
When 'Gag' refers to a joke, it is often combined with verbs such as 'machen' (to make), 'erzählen' (to tell), or colloquially 'reißen' (to crack).
Er versucht immer, auf Partys Gags zu reißen.
He always tries to crack jokes at parties.
Besides 'Witz' (joke), 'Gag' can also mean a clever trick or a surprising special feature. The phrase 'der Gag an der Sache ist…' (the gimmick/twist of the thing is…) often introduces the explanation of such a feature.
Der Gag an diesem Stift ist, dass er auch als Werkzeug funktioniert.
The gimmick of this pen is that it also works as a tool.
idea
'die Idee' and 'der Gag' can both mean an idea. 'Idee' is neutral and can fit any topic: work, everyday life, art, or planning. 'Gag' is more specific. It is either a funny idea meant to make people laugh, or a surprising gimmick that gets attention. The words can be confused because a 'Gag' is often also an idea. But not every 'Idee' is a 'Gag'. If something is mainly useful or serious, you say 'Idee'. If it is meant to be funny, surprising, or eye-catching, 'Gag' fits better.
