What does 되게 means? How is it used?

Question

Answer

There are two meanings in it.^^ 

1) kinda slang meaning "very" "really" (= 非常，实在，真的。。) 
It's very hot today 
> standard one : "오늘 진짜(=정말) 덥다." 
> using the slang '되게', "오늘 되게 덥다." 

2) It could be a part of "되게하다" (which is sorta conjugation of "되다(to become)") 
meaning "to make something happen" or "to make somebody something" 

He made his son a doctor. 
그는 자기 아들을 의사가 되게했다. 
= He forced his son to become a doctor.^^
