Steiner is a ubiquitous word that can mean anything that the sayer wants. It is much like the variety in swear words. Though Steiner is a safe word to use around family, the sayer can change the tone, tense and declension of the word (I.E. Steinerer, Steinerous,Steinering) to give it a rather offensive sound.
Usage
Steiner most of the time refers to a person or persons, but in rare occasions can be used as an exclamation both directed at someone.
“Wow, that girl sure is quite the Steiner once you get to know her.”
