パトワごがっかコミュのKetchy Shuby

わからないのでどなたか教えてください。
ピータートッシュの曲「Ketchy Shuby」
この曲非常に好きなんですが･･･
Ketchy Shubyってパトワ語でしょうか？もしかして英語？もしかしてKetchy Shubyで1つの単語？？？ﾊﾃﾅﾊﾃﾅ？

昔知人に質問したことあるんですが、「catch and release」のようなニュアンスの答えだったような･･･。
しかし歌詞を見てもなんについての歌かあまり想像できず･･･。
どなたかご存知の方、よろしければ教えてください。
参考までに歌詞載せておきます（英語詞ですが）。

Ketchy Shuby
By: Peter Tosh

Come back we play some ketchy shuby
and when you shuby you feel ketchy
and when you ketchy, don't make it drop
because if it drop, it will pop
and if it pop, no one can mend it
cuz if they mend it, you can easily bend it

So we a go ketchy ketchy shuby shuby tonight
