damn / crap
A colloquial exclamation of annoyance, disappointment, or mishap.
Mist! Jetzt habe ich den Bus verpasst.
Damn! Now I've missed the bus.

Careful, 'Mist' is a false friend! It does not mean the English word 'mist' (fine fog). The German word 'Mist' means animal manure or is a colloquial expression for annoyance or poor quality.
So ein Mist, ich habe schon wieder den falschen Knopf gedrückt!
Damn it, I pressed the wrong button again!
The meaning of 'Mist' depends strongly on context. In agriculture, it is a neutral term for fertilizer. In everyday language, however, it is an informal, colloquial word for annoyance or something bad.
Der Bauer fährt den Mist auf sein Feld.
The farmer drives the manure onto his field.
As an exclamation of annoyance, 'Mist!' usually stands alone at the beginning of a sentence, often followed by an exclamation mark. It introduces a statement about the mishap.
Mist! Jetzt habe ich mein Handy zu Hause vergessen.
Damn! Now I've forgotten my phone at home.
In the meaning of 'Unsinn' (nonsense) or 'schlechte Sache' (bad thing), 'Mist' is often used in fixed expressions. Typical ones are 'Mist bauen' (to mess up / make a mistake), 'so ein Mist!' (what a mess! / damn it!), or 'Mist erzählen' (to talk nonsense).
Ich habe gestern bei der Arbeit totalen Mist gebaut.
I really messed up at work yesterday.
damn / damned
'verdammt' and 'der Mist' can both express annoyance or frustration and are colloquial. The difference lies in their form and use: 'verdammt' is often used as an intensifier before an adjective, or as an exclamation when you are angry. 'Mist' is a noun and is often said as a short exclamation when something goes wrong, or used for a bad thing. They can be confused because both occur in annoying situations. 'Verdammt, das ist schwer' (damn, that is hard) intensifies the statement. 'Mist, der Bus ist weg' (damn/crap, the bus is gone) expresses the mishap.

Mist, ich habe mein Heft im Bus vergessen.
Damn, I left my notebook on the bus.
Diese Aufgabe ist verdammt schwer.
This task is damn hard.
