Phrase finder suggests that the saying originates from the dictionary definition of the term "suck-egg" which refers to:

- An animal that is reputed to suck eggs, e.g. a weasel; figuratively. an avaricious person.

It is also considered to be a dismissive insult similar to the term fuck off but is less abrasive.

TL;DR

It's a less-abrasive dismissive insult intended to be directed at someone who is being greedy.
