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, hence the term "giggling like a schoolgirl", 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.
