English to Chinese Other Slang Taiwanese Hokkien slang

Hello. I am interested in and am doing research on Taiwanese Hokkien youth language-youth, street and college slang.

Taiwanese Hokkien is the form on Min Nan spoken in Taiwan.

I'd like to know, how do you say "mad dog" in Taiwanese Hokkien besides 瘋狗?

a "mad dog" is a rebel, non-conformist, one who refuses to accept their role in society.

Please let me know. Thanks.
