Is Google A Proper Verb?

[NYAD]

I know it's a proper noun (the name of something). A Google search (adjective?) for the answer was unsuccessful. No one will commit that proper verbs exist.

[Peter Pedant]

Remember boys and gurlz - is gurl a common noun ? - dictionaries in English declare use
and do not prescribe right or wrong.
so.... disinterested has a meaning of fair and unbiassed but also is recorded as having the (wrong) meaning of uninterested as people use it as such

presumably also temerity meaning timidity as well as er courage
