Bedeutung
To occur unexpectedly for someone.
Kultureller Hintergrund
Danes often use this phrase to downplay their own shock. It's a way of being 'nede på jorden' (down to earth) about one's own lack of knowledge. In Greenlandic Danish, the phrase is used similarly, but often in the context of nature's overwhelming power, which is a constant presence. In meetings, using this phrase can be a polite way to signal that a topic wasn't on the agenda and you need more time to process it. Headlines frequently use this phrase to create a sense of drama or to highlight a 'scandal' where authorities were unprepared.
Use 'Helt'
Danes almost always add 'helt' (completely) to this phrase. It makes you sound much more native. 'Det kom helt bag på mig' is 10x more common than just 'Det kom bag på mig'.
The Object is Mandatory
Never just say 'Det kom bag på.' You must say who it came behind. If it's you, say 'mig'.

10 FragenYes, but it's more about the *unexpectedness* than the *joy*. If you win the lottery, it 'kommer bag på dig'. But if you give a friend a gift, you 'overrasker' them.
It's neutral. You can use it with your boss, your grandma, or a stranger on the street.
'Overraske' is a general verb for surprise. 'Komme bag på' is an idiom that specifically emphasizes being caught off guard or unprepared.
Yes! You can use it for animals too if they are visibly surprised by something.
In standard Copenhagen Danish, it's very soft, almost like a 'y' or silent. In Jutland, it might be harder.
Yes: 'Jeg er sikker på, at det vil komme bag på ham.' (I am sure it will surprise him.)
Prepositions in idioms are often arbitrary. In this case, 'på' indicates the 'surface' or 'person' the surprise lands on.
Very much so. It's common in journalism, novels, and emails.
Not necessarily, but because being unprepared is often slightly stressful, it is used for negative surprises slightly more often than positive ones.
