We would say this is another run-on sentence.

What do we say if someone has drunk water from a glass by touching it with his mouth, like in hindi we call it "jhoota" means it is not cleaned and nobody else shoud use it before washing, so what should we sqy in english?
"It's not clean", or "It's been used".
So there is no unique word for it.
You could use "soiled" which is one of the meanings of "jhoota". More usual would be "dirty".
