Thought to be a name for blonde children, (coming from the word used to describe flax rope); it actually is only fitting to children with hair so light, it is literally "white".
This color generally goes away between 2-5 yrs old.
Ex. I had four children, all blue eyes, but only three of them were towheads.
In colonial times, families grew their own flax to make into fabric for clothing. Transforming the flax into thread was a complicated, involved process with many time-consuming steps. After the flax was harvested, it was soaked in water for several days to soften it so the inner fibers could be removed from the stalk. To separate the long, thin fibers from the shorter, coarser ones, the flax was pulled through a bed of nails or combed in a process called "towing." The shorter fibers that were extricated were of a lesser quality and were called "tow." This led to the term "towheads" to describe people, particularly children, whose hair resembled these strands.
Nickname given to bales of marijuana thrown overboard or out of airplanes. Origin is reportedly from members of the US Coast Guard in the area of Southern Florida.
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
I had a trucker's tan after driving for 10 straight hours on a sunny day.
