I have to admit, there’s a line in the song where the female singer asks if there is something in the drink that seems, in the age of “Roofies” to be a little “date rapey.”
OTOH, that doesn’t apply when Dean Martin sings it because you know she’s just asking about how he mixes his drinks.

That’s all it means when anybody sings it.
Yes, the original implication is that he spiked her coffee with some liquor or something like that. Not exactly gentlemanly, but far from “date rapey”.
