What is a "sucker"?

A sucker is a specialized organ or structure found in certain animals used to attach themselves to surfaces or other animals. Suckers are most commonly found in cephalopods, such as octopuses and squids, and in fish, such as catfish and lampreys. These animals use their suckers to hold onto prey, climb, or attach themselves to rocks or other objects in their environment. The suckers are typically composed of circular muscle fibers, which can contract and expand to create suction, as well as specialized tissues that secrete adhesive substances to increase grip.

Slang

What is the origin of the term "sucker" and how is it used?

"Sucker" meaning an unspecified thing comes from the same casual slang extension where the word functions as a filler noun, similar to "thing" or "item," often with emphasis. This usage became common in informal American English in the late 20th century. It is neutral to informal in tone, with little or no insult intended depending on context.

Examples
This sucker is heavier than it looks – help me lift it.
