"Jiayoumama" doesn't have a specific meaning in English or any major language I'm familiar with. It appears to be a combination of Chinese words or names:

1. "Jiā yóu" (加油) in Chinese means "加油" which can mean "go加油" or "add oil", often used as encouragement or motivation, similar to "come on!" or "keep it up!"

2. "Māma" (妈妈) means "mom" or "mother" in Chinese.

Without more context, it's difficult to determine if this is a name, phrase, or something else. If you meant to say something specific or if you have more context, please provide additional information and I'll do my best to help!
