Term for strange words?

I often hear strange words that are not in the dictionary. Such as slather. "She slathered on sunblock while at the beach"

Is there a term in grammar for strange words? Would this be a slang, jargon or something else?

A word that is made up of a combination of two words is called a blend. slather derives from blending slap and lather => lather, meaning, to spread quickly.
