Why do calypsos maid giggle when they see o?

Answer 1

Perhaps because Odysseus is sleeping with the nymph Calpyso. If the nymph giggling is Calypso, it could be because she is in love with Odysseus.

Answer 2

Calypso maids giggle when they see "o" because it alludes to the shape of a man's mouth when he is saying the letter "o," which is seen as humorous to them. It is a playful and flirty reaction that adds to the fun and light-hearted nature of calypso music and performance.
