Species and nations have a lot in common. What, for example, is a German? The tribe has a shared and guttural means of communication that interrupts intercourse of most kinds.
What does the last part mean? It could mean they interrupt each other in conversation, but that's not unique to Germans - Australians do that too.
Or it could mean they talk during sex, I believe some people do that.
I should know the answer, because I'm half-German, as you can see here. This week's picture was taken a long time ago on the day I finally gave up trying to grow a moustache, and shaved it off in stages. The half-nekkid part is the top lip.
