look up any word, like blumpkin:
 
1.
A person with very light (almost white) blond hair, "tow" being flax or hemp fibers. Tow-headed, along with fair(-haired) and flaxen-haired, is a tradional way in the English language to refer to blond hair or lightly-colored hair, having come from its old Germanic roots (which are quite rare).

2.
tow headed is literally "flaxen haired". This meaning of tow comes from Middle Low German touw (which means "flax, hemp fiber"). This probably went back to the prehistoric Germanic base *tow-, *taw "make, prepare" (source also of English tool), in the sense "make yarn from wool; spin".

4.
The inevitable blonde douche bag that is often found on overseas academic trips. Has a tendency to bite his lower lip and a habit of infecting the social mannerisms of others with his own douche-baggery (douche-baggery being a term he believes he invented himself). Smokes like a chimney and habitually quotes adult cartoons in an attempt to be funny.
Person 1: "Did you see that guy over there? He knows the word for ashtray in seven different languages!"

Person 2: "Wow, what a towhead."
