Can 'Dupe' be used as a verb instead of 'Duplicate'?

Solution 1:

The Oxford Dictionary acknowledges dupe as an abbreviation of duplicate:

verb & noun

Short for duplicate, especially in photography.
[AS VERB]: how to dupe 35 mm slides on to 35 mm film
[AS NOUN]: black-and-white dupes

The application of dupe seems to be expanding beyond photography.
