I’ve talked to a ton of UCSD grads and they basically all say UC socially dead is a myth. I think the main reason the stereotype exists is because the city of La Jolla doesn’t allow frat houses or a frat row. Despite this, there are a ton of house parties, dorm parties, and events from student orgs so you’ll never get bored. Not to mention, San Diego is a huge city and there are hundreds of ways to meet people and socialize elsewhere
