Where Do They Come Up With This Stuff?

"Let's go tussle without weapons!"


This phrase came out of my young son's mouth this afternoon.  I had to call him back to ask if he said "wrestle."  No, he said "tussle."


Who says "tussle?"  Apparently the neighbor kid, also 5 years old, taught Paul the vocabulary word.  And how to use it properly in a sentence. 


Tussle.  Huh.
