Parenting: Speaking their Lingo

I thought that I had it covered - When kids say "sick" they actually mean "great" thus, "thats sick Dad!", means "thats great Dad!".
 
I was wrong.
 
I've just learned that "sick" actually means "sick" in the traditional sense - but its actually "s-i-i-c-k" or the elongated form of the word "sick" that is actually used to means "great". 
 
It makes sense really!
 
Guess that goes for words like "w-i-i-cked" too??

By the way, I have learned that "Gee thanks Dad - you're the best Dad in the whole world" has to be up there with the best words that you'll ever hear.
