Biker Gang
Motorcycle Gang, Japanese Bikers, Bosozoku
noun
A tribe that runs wild (暴走) is what the Japanese call a biker gang. Just imagine them riding around on their bikes, running wild. They're also close, like a family. How nice!
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
暴走族は、アライグマをひいたことを認めた。
The motorcycle gang confessed that they had run over the raccoon.
暴走族に入るなんて、ゼッタイにゼッタイに認めませんよ。
I will never ever acknowledge your joining of a biker gang.
