anorak
LDCE:
1. especially BrE a short coat with a HOOD that
keeps out the wind and rain
2. BrE informal a boring person who is interested
in the unimportant details of a particular subject
and does not know how to behave properly in social
situations
I wonder what are the American equivalents.
About 2.
Is this understanding correct?
'Nerd' is used both in the UK and US.
Thank you.

It's correct- you can also call an anorak a trainspotter in the UK.
