Laugh of Love

When a character (usually female) develops a tendency to giggle or even laugh when around their love interest or when they do something romantic, such as holding hands. This may be accompanied by a blush.

Giggling is also a sign by imagining themself doing things with their lover. It shows their obsession with their love.

Examples

 * In Spider-Man, the famous kiss in the rain scene between Spider-Man and Mary Jane, she giggles as Spider-Man swings off.
 * In Spider-Man 2, Mary Jane is laughing happily as she runs to Peter's place in her wedding dress as she's realised that he's the one she truly loves.
 * Spider-Man 3, Ursula giggles briefly when she's feeding Peter cookies while he's talking to Dr. Connors over the phone. Later, Betty Brant laughs nervously when Peter, who's under the symbiote's influence, starts hitting on her at the Daily Bugle.
 * In The Amazing Spider-Man, Peter and Gwen tend to laugh around each other as they gradually fall in love.
