Origin and History of “Heater” as Slang
The slang word heater comes from the idea of something being “hot.” In English, “hot” has long been used to describe something popular, exciting, or successful. Over time, people began using heater to describe anything that was performing at a very high level.
The phrase “on a heater” became especially popular in American sports. Commentators and fans used it to describe athletes or teams that were winning repeatedly or playing exceptionally well.
Another meaning of heater a slang term for a firearm has existed in American English for many decades. It likely developed because a gun becomes hot after being fired. This meaning is still seen in some rap lyrics, crime fiction, and older slang, but it is much less common in everyday conversation than the positive meanings.
Today, the most popular online meaning of heater is simply something outstanding or impressive, especially a song, meme, video, or performance.
