In English, one would say "The weather is so damn cold!" or "The S-Bahn strikes happen so frigging often!" Is there something similar in German?
I know that, in some cases, you can use an absolute superlative, like arschkalt, or just say sehr kalt; but that feels a bit tame to me, and doesn't always express the depth of my emotion.
You can use the literal translation:
verdammt kalt
Or this one is also commonly used:
hammer-
as intensification or maximization prefix.
I've heard mega quite often but I wouldn't use it.
Es tut so mega weh!
sounds for instance teenager-vocabulary.
You can use any number of different words: verdammt, verflucht, or (if you'd rather avoid swearing) you could use heftig, extrem, gewaltig, and to add even more emphasis: wirklich heftig, or wirklich extrem. More colloquial would be echt extrem.
One other, very commonly used intensifier is derbe, other ones include voll/total (roughly equivalent to fully or totally in that context) or krass. These are a bit more colloquial, though.
Das ist doch derbe unnötig! Das Wetter ist derbe kalt, man. Passiert derbe oft, nicht?
Krass unnötig. Es ist doch fast nicht zu glauben, wie krass gefährlich diese Straßenkreuzung doch tatsächlich ist …
Voll bescheuert. Total unnötig.
