Special events and other funny days

World Kissing Day is July 6 every year. The practice originated in the United Kingdom, and was used worldwide in the early 2000s

If you think Valentine's Day has a commercial aftertaste, "World Kiss Day" or "International Kiss Day" may be a good option.
The idea behind the day is to remind people of the simple joy of "kissing for the sake of kissing". That is in contrast to a foreplay.
However, it is a golden opportunity to kiss one you would like to get to know much better to check the conditions.
If things go awry, you can just apologize with "it's the big kissing day".
