What does the word 「へそのごみ」mean?


It is a dialogue said by a boy who watched and criticized a theater play. I
also translated it myself for checking if I correctly understand the context.

わるいけどお先にしっけいするぜ。 --> It is not good but I have to say goodbye.

こんな茶番劇見てるなら --> If I have to watch this foolish play...

反省房へとじこもって **へそのごみ** でもとってたほうがよっぽどましだよ --> I think secluding myself in
repentance room and doing/taking..... would be much better.

I'm not sure if it means doing/taking unimportant thing.




Put it simply, he is saying that spending his time cleaning up his bellybutton
would be a much more productive use of his time than watching that lame show.

  * へそのごみ = bellybutton trash 
  * とってた = to pick 
  * ほうがよっぽどましだよ = is the much better thing to do. 

He doesn't mean that he really wants to clean his bellybutton, it's just his
way to insult the show.

わるいけどお先にしっけいするぜ。

> Sorry but I'm getting out of here.

Literally: sorry but I'm gonna be rude first. It is a very casual way to say
「先に失礼します」and basically just mean that you are leaving first(which I suppose is
seen as rude by Japanese standards.)  
わるい can be used to say sorry.(and not "this is bad".)
