I sometimes watch this anime called Crayon Shin-chan in Portuguese (in which it is simply called Shin-chan). Flirty as he is, Shinnosuke (its main character) is often inconveniently messing around with women. Sometimes he walks up to them and, as if to break the ice, asks them "Do you like peppers?". After this either the women get very embarrassed or his mother knocks him in the head (or both).
Also, in one opening theme he sings that "pepper tastes so bad".
Is this something specific to the Portuguese version of the anime?
Is its only significance related to his childishness (him being a five-year-old child)?
Or is it supposed to mean anything other than that (and makes more sense in Japanese)?
