I don't think you need a happy-happy-happy memory to perform the charm.  Harry imagined Umbridge getting sacked to produce a patronus, remember?  That's not a genuine happy memory, but rather a righteous ha-ha wishful thinking kind of thought.  Following that logic, all Snape would have to do is imagine expelling Harry to produce a patronus.
