o.o well thats odd he`s talking in this weird old dutch farmers dialect. Being dutch I can translate this to your a sick person and you make a bad expression.
As a sidenote I fully disagree and ask you to disregard the fellow dutchman >.>
Uhm I have no idea what that actually says, but google translate said something about, "You're a sick person" and something about rotten heads. XD So maybe an insult?
