Laugh of Love

Sadly for Dave, it's all in his imagination.

This trope is when a character (usually female) develops a tendency to giggle or even laugh when around their love interest, particularly when the love interest in question is joking around, or when they do something particularly romantic, such as holding hands. This may be accompanied by a Crush Blush. The Smitten Teenage Girl is particularly prone to this, as are the Sickeningly Sweethearts.

Giggling is also a sign of the character imagining themself doing things with their lover. For... less than stable characters, it shows their obsession with their love, and can overlap with Giggling Villain in extreme cases.

This trope tends to be common in romantic comedies.

This is Truth in Television (obviously).

  • In Naruto, there are at least two instances where Hinata Hyuga giggled after her crush and, eventually, her lover Naruto said something foolish. The first time was at the end of the first part of the Chuunin Exams. The second time was in The Last: Naruto the Movie, while the two of them were investigating an abandoned shinobi village.
  • Pokémon:
    • In "Under the Pledging Tree", when Ash asks Serena what gifts she's planning to get while she's thinking that the two of them are on a date, she quickly replies "I'm not sure yet!", while chuckling nervously.
    • In "Party Dancecapades", Serena mentally chuckles nervously while thinking of dancing with Ash.
  • In Princess Mononoke, a lot of the women of Iron Town giggle and blush when they're around Ashitaka.

     Fan Works 
  • In Child of the Storm, though she'd probably dismember anyone who said it, Carol tends to laugh, even sometimes giggle, a great deal more when she's around Harry. Of course, this is often at him, but it's still affectionate.

     Real Life 
  • It has been noted that when a person is in love with someone else, even their lame jokes will become hilarious to the person in question, and they tend to laugh more when they are around that person. As a result, this is a reliable means of identifying if someone is in love with you (especially if the person in question is a girl).
