That's because it needs a semicolon:
Buffalo buffalo Buffalo buffalo; buffalo buffalo Buffalo buffalo.
Also it isn't a very good sentence because you've said the same thing twice.
It should read:
Buffalo buffalo buffalo; Buffalo buffalo buffalo Buffalo buffalo.
Translation:
"Buffalo" is a place, a noun (more or less meaning bison), and a verb (to harass or bully). So what it means is:
Bison bully bison; Buffalo bison bully Buffalo bison.
