skimmer

A skimmer can be several things. Most often, it is a tool that removes things from the surface of a liquid, like a pool basket that catches leaves or a kitchen spoon that lifts foam or fat from soup. It can also mean someone who reads very quickly and only takes in the main idea. In a crime context, a skimmer is an illegal device that steals bank or credit card data, and sometimes the criminal using it is called that too. In other cases, the word can also refer to a seabird or to a light boat that moves across the water's surface. Context tells you which meaning is meant.

The word "skimmer" has surprisingly diverse meanings, all revolving around the idea of taking something from a surface or quickly passing over it. Originally, and still commonly, a skimmer refers to a tool or device designed to remove things floating on liquid. A pool skimmer is probably what comes to mind first—that basket that collects leaves and bugs before they sink. In the culinary world, a skimmer is a flat, perforated spoon used to remove "scum" or fat from the top of a pot. On a much larger scale, industrial skimmers are used for environmental cleanup, like removing oil from the ocean's surface after a spill.

In a literary sense, a "skimmer" is someone who reads quickly and superficially. Rather than delving into every nuance, they skim through text to find the main points or specific keywords. While useful for a quick briefing, you might hear a teacher warn, "Don't just skim the report; read it thoroughly!"

Unfortunately, "skimmer" has a negative connotation in the world of financial crime. A credit card skimmer is an illegal device attached to ATMs or gas pumps that steals your card information during a transaction. The person behind the scheme can also be called a skimmer, as can someone who illegally pockets a portion of cash receipts before they are recorded.

Finally, the term extends to the natural and mechanical worlds. A "skimmer" is a unique seabird that flies low, dipping its long lower beak into the water to catch fish. Similarly, in boating, a skimmer is a fast, flat-bottomed boat designed to glide across the surface of shallow water rather than plowing through it. Whether you are cleaning a pool, browsing an article, or watching wildlife, the context will tell you exactly which "skimmer" is at work!
