If Boimler said it, Spock would probably go and ask one of his friends to have him try one of those "marsh melons" and would probably be corrected. It just seems like a very in-character thing for Ortegas to do!
Now we need a scene in SNW where Ortegas decides to play a joke on Spock by calling them marsh melons and giving everyone else (in picturing Chapel, Uhura, M'Benga, and Sam Kirk) a "shut up and make him believe it" look.
"What's with people liking the thing I don't like?"
Seriously, people. Can we not gatekeep Star Trek? Does Enterprise have its problems? Absolutely, but so does literally every other Trek show. Every series has its own ups and downs, and while Enterprise might have issues, it has redeeming qualities, too. No one is going to make you like Enterprise, but don't be critical of other people because they like it.
Here's the thing though... it isn't factually incorrect, and taken together with how Ethan Peck has played the character, this line could just be viewed as Spock's attempt at a joke.
When she and the alternate Kirk went on their little time travel adventure, the episode ended with La'an calling Kirk to ask about some kind of bullshit info she needed for Sam Kirk's file.
I saw the whole security excuse as an extension of that.
