Brun's internal thought processes in today's strip are, IMO, something like this:
PANEL 3: "Hmm... Curious, I seem to have done something socially inappropriate here."
PANEL 4: "From Elliott's reaction and Renee's words, it appears like making timepieces sound like sexual characteristics is taboo somehow. However, given how I misinterpreted the whole 'smelling each other' thing, I'm not that sure I can trust this impression. I must verify before I go any further."
PANEL 5: "Taboo confirmed and registered on my 'socially inappropriate' mental index-file."
BTW, it is cute and in character that Brun wouldn't use slang terms but prefers to use medically-correct terminology. She has to, of course; otherwise, people might think she's talking about male birds!
