Hungarian to English Other Slang

I
am trying to get help with a Hungarian phrase. I'm not sure
that "phrase" is the right word, I think a better word might
be "curse".

Since I don't know how it is spelled in Hungarian, I will
try to spell it out in English letters, and if any one can
figure it out, please help me.

Here goes: usta kutcha faya neta keni

I think, it means something like: "you dirty dog", but I
could be totally wrong.

Obviously I don't know where a word ends and where the next
word begins. It is kind of a joke in my family, so I would
greatly appreciate it if someone could help.

Thanx,
Gigi
