Summary
The ellipses question mark is an altered form of the classic ellipse, and although it only has two dots, it is not to be confused with the two-dot.
Texting Uses
In texting, the ellipses question mark is commonly used by teenagers (if an older person is confused, they will use multiple question marks or an exclamation question mark).
Context
If a person uses a ellipses question mark, they are often confused as to what is going on or being said. It can also indicate sass or attitude. The ellipses question mark is to be always used at the end of a sentence, as it is a form of punctuation.
Examples:
“What are you talking about..?”
“Are you sure..?”
