Oh now I do recall, we were just getting to the part Where the shock sets in, and the stomach acid finds a new way to make you get sick I hope you didn't expect that you'd get all of the attention Now let's not get selfish Did you really think I’d let you kill this chorus?"

This part is like him telling her no when she tries to come back or feels bad about what's going on. I think the song in general is like "Hey, you messed up and you're not getting me back."

"So testosterone boys and harlequin girls Will you dance to this beat, and hold a lover close? So testosterone boys and harlequin girls Will you dance to this beat, and hold a lover close?"

I think this is like advice.. saying to stick by who you're with. A lot of people make the mistake of doing something dumb and then later realizing what they had before was a lot better, so maybe he's saying not to do what his girl did and take the relationship for granted.

In general the song is him shutting her down, and then telling everyone else not to mess it up either.
