Cartoon-O-Rama, Web-O-Rama, Football-O-Rama
O-Rama的含义，来源和用法
參考答案:O-Rama is when a lot of people do something at the same time. It is not considered good English and I would avoid using it myself. The term is mainly used in USA.
For example a Cartoon-O-Rama could be when a TV station shows cartoons all day. Football-O-Rama could be a lot of people coming together to play football, or having a lot of football matches on TV in a row.
Hope this is helpful! I can't explain in Chinese sorry.
I think though it is not a good English term to use, it is good to understand it but I would avoid using it myself.
I hope this gives you some idea?
