Is this a good sacrifice to stop the boungcloud(and don't say it's bongcloud).

Yes, that should do it... very Korchnoi!

i dunno what if your anti-boungcloud gambit is declined? seems he easily has either 3.Kd3 or Ke3 or Kf3

I think any response here will raise a few eyebrows.  I believe someone came up with an improved variation of the Bongcloud with 1. f4 and Kf2, you might want to see if the moxin anti-bongcloud (if you have to call it the boungcloud, you might be REALLY bored!) works on that line as well. 

actually it was lenny himself who suggested that line i think. in a post he wanted to clear up that he didn't just play the same opening
