What shitty dictionary is that from? Merriam-Webster?
I mean, you could colloquially use it in a bastardized form, but then you're being a moron who is destroying the entire purpose of language: to communicate effectively.
P.S. If you found the second definition in a "colloquial" or "informal" part of the definition, that means shit-all. All that's saying is, "Hey, some people don't know what the fuck this word really means and may misuse it under the assumption it means this."
Sorry, English major rant!
OED jumped on board also. Languages are literally always evolving.
