Loli Watching

It's similar to people watching, or bird watching. The last two are things you do when you're an old gramps who doesn't know how to use internet or smart phones, & who's life is incredibly boring... But with loli watching, anyone of any age can enjoy. Some even find it more enjoyable than surfing the web. Like bird watching, cameras & binoculars are optional.

Guy 1: "Hey brah, wanna go to the local public pool to do some loli watching?"
Guy 2: "Sure bro, can't say no to the cuties!"
