Where the word comes from
The term dates to racetracks, where odds were written on chalkboards and the heavily backed horse's price was rewritten so often the number smudged. Chalk came to mean the favorite, and it stuck long after the boards disappeared.
Chalky tickets
A chalk parlay is one built entirely from favorites. It feels safe and pays little, and because every leg carries the same juice, stacking favorites compounds the house margin rather than diluting it. Public money leans chalk, which is part of why favorites are often priced slightly worse than they should be.
