我系从青山出来蹬脚嘎
[wŏ xì cóng qīng shān chū lái dèng jiăo gā]
This sounds like it could be nonsensical slang or intentionally misspelled text for playful effect, which might not easily translate into English but suggests a carefree attitude. Possibly means coming out of seclusion or nature (from the green mountains) with an upbeat and light-hearted step.
