Nearly 9,000 Chileans kissed their way into the record books after smooching simultaneously in a Santiago street.
More than 4,400 couples took part in the event
The men and women, most in their 20s, poured into the cordoned-off road in Chile's capital to kiss for at least 10 seconds in their record-breaking bid.
With more than 4,400 kissing couples, they easily beat the current record of 1,588 pairs who puckered up in Sarnia, Ontario, Canada, in February 2000.
An event official said two well-known photographers organised Chile's bid.
Chile is one of Latin America's most socially conservative nations.
Yet there are signs things are changing.
Last year, more than 3,000 people turned up on the same street one cold winter morning to be photographed naked.
"You never used to see this kind of thing, people looked down on it," said Fiona Ceballos, 23, after kissing her boyfriend.
"I think Chileans are coming out of the closet," she was quoted by Reuters news agency as saying.
