Do you know how to say:
"I have so much homework! What a pain (in the butt)!"
Okay, well here we go...
Here is the breakdown:
めっちゃ= This is the Kansai dialect 「関西弁 （かんさいべん）」 version of とても, meaning very (or "a ton"--as in this case)
ある＝This is the dictionary form of あります, meaning to have.
ねん＝This is not 年（ねん=year), it is again from the Kansai area. It is like よ （I think), like あるんだよ which adds emphasis.
スゲー = This is the slang for すごい, which means：terrible, great, amazing, wonderful, dreadful
めんどうくさい ＝ This means: a pain, or pain in the butt. But the dictionary will give definitions of tiresome or
bother, bothersome. And it means that too, but it can mean "pain (in the butt)"--because it's saying the same thing.
Okay, so if you want to know the standard Japanese version (not Kansai Dialect), then I think I would say something like:
Have fun using it.
You know really well the Kansai dialect. I have that one. Some Japanese people like it but some of them are scared of it, especially people who live in Kanto region. I don't care of it though. I speak it anywhere I go. I love it.
