May speaks fluent vulgarity. Maybe even a pidgin version of Army Creole. But, being non-biological, many of the things conventional (ie, human) vulgarity mentions really have no first-person referent for robots.
In today's example, May says "shitnuggets" when compaining about probably never getting Hank the Dismemberer's autograph.
But May has never experienced constipation in her life. She's never experienced that literal pain in the ass. She's never experienced the horror of having to use an enema or a suppository or when desperate even cruder measures to get something out of there, nor the revulsion we feel and the stench we have to endure when we have to get a screwdriver or something and break one up before the bits are small enough to flush.
I realize she's just using it as expressive language, and so do humans most of the time, but ... if your physical incarnation is immune from the actual unpleasant events they refer to, I think words like that just couldn't possibly have exactly the same meaning for the mechanically-gifted set.
On the other hand, when people say "fuck" to me I am always reminded how nice that is, and usually it brings up pleasant memories and makes me smile. Maybe I'm just weird about hearing what people say rather than (or in addition to) what they mean.
