However long I live in Germany, it seems that people spot me for a foreigner the moment I open my mouth.
The problem is that I speak a fairly accent-neutral grammatically correct German. Stop sniggering at the back there! This of course, is a dead give away. Real Germans just don’t talk like this.
The trick is to find something other than Hochdeutsch to have as your accent.
This blog already suggested that famous dialect: Imbißdeutsch as a way of passing off as a local.
To complement this, I’d like to suggest another form of German which will allow us to blend in – this time with a group which we really wouldn’t want to spot us as being foreign. The neo nazis.
