Gatekeeping
When someone limits people from certain hobbies/memories/activities over something as small as the year that they were born in. Gatekeeping is frowned upon, so I don't recommend doing it. It's also a really stupid thing to do.
Example of gatekeeping: Anyone born in 2007 is a tide pod eating 2010 kid who doesn't deserve to have a opinion. Please don't gatekeep, its really rude and immature. I just wanted to show an example of how gatekeeping is used.
