1.
a sex act similar to fellatio but when the man takes control by forcibly moving his penis with a high velocity in and out of the mouth/throat so as to make a "uck-uck" sound in the process. Hence the term duck duck.

Note: can be used as either a noun or a verb.
He took her round the corner for a quick duck duck.
