Just thought "Go to hell" is very English way of putting a curse on someone. If you say the literal translation to a Korean person in practice, you'll be rather smocked. I'd say just "저리 꺼져", similar to *uck off. I know lots of swearing expressions including "creative" ones. So if you want to know something more, just shout out to me. ;)
Ah, and another way of saying "You are not funny" is '안 웃겨'. Slang : '썰렁해'
Hope it helps ;)
*smocked → mocked
