Mongo in (British? West country which happens to retain relatively more Saxonism and other Germanic influence?) English too actually, or more often 'mong', but it's not prevalent enough that I've made the link before.

In German it's the only possible meaning, unfortunately... ("Mongo" is short for "mongoloid")

I'm not aware of any other meaning in English either.
