Hi Ian,
to be frank, you did change the meaning a bit I think..(but don't worry!) by writing:
or, how do you say it, be like the rest of the gang ?? !!!!
The swedish origin is more like a question to the people, he/she is asking the rest of the gang what they are thinking about his statement, if they agree.
about:
'It's just to descend upon in next round of the clown about'
the meaning is when you take part in something, or show up without a invitation, you just go there or descend upon.
clown about = similarity to students' farce
my suggest to corrections is:
or, what do you say,the rest of the gang ?? !!! It's just to show up in next round of the clown about ...
What do you think of this Ian
