A beeline is the swiftest, most direct route between two points. If you are shopping at the mall on a weekend afternoon and you see an empty parking space, you should make a beeline for it or risk circling the lot for hours.
The word beeline combines the words bee and line. The idea behind the word is the belief that a bee, when it is done feeding, will take the shortest path back to its hive without delay or meandering. So beeline not only has the sense of being a direct route, but also that there is some haste behind the action. If you make a beeline for the chocolate at a party, you went straight to the dessert table without eating dinner first.
