Hi,

Another line from fairy tail episode 13. It's said (by Natsu) about his colleague who got beat really bad and couldn't move anymore.
How lame...you got butt-whupped good.

Does good mean so/very much here?

 

Yes it does.

 

Thanks, by the way, is it colloquial?

 

Yes, the entire sentence is VERY informal.

 

Thanks for your help.
