What does it mean to eat too much oil in Sichuan dialect?

Earlier, when I was not rich, I often didn't eat meat for ten days and a half. You can't see oil and meat if you eat regularly. Once someone invites you to dinner, meat is indispensable. So Sichuanese vividly described the earlier banquet as "eating too much oil", which means "having a rare tooth".

Of course, this is just a way of saying that there was a happy event in those days, and now the cook is invited to his house to make a banquet. Not at present. Hehe, it's a bit tacky.
