What does whizzer mean?
Whizzer is an informal English noun with two related but distinct uses. Most commonly, it means an exceptionally able or successful person, especially someone with a particular skill: one might call a gifted programmer or mathematician a whizzer. In this sense it is close to expert, whiz, and virtuoso, but it usually carries a more casual, enthusiastic tone than a word such as specialist. Less commonly, a whizzer is something moving very quickly, especially a bullet or similarly fast object. The word is used in both British and American English, though the alternative spelling whisser is also encountered. Its form reflects a productive root used for both rapid motion and exceptional ability. The word is memorable because it shifts easily between the human and physical senses: a whizzer may be the brilliant colleague who solves a problem or the projectile that streaks past in an instant.

Where does whizzer come from?
Whizzer was formed in 19th-century English by adding the suffix -er to the root whiz or whizz. That root was used both for rapid, hissing or buzzing movement and, in colloquial speech, for an exceptionally able person. The suffix adapted it to a noun, and the resulting word came to denote an expert as well as a fast-moving object; whizzler, an old term for a fast boat, belongs to the same root family.
How whizzer is actually used
The expert sense is informal and usually enthusiastic or complimentary. The less common sense for a rapidly moving object can sound colloquial or literary. The alternative spelling “whisser” is also encountered.
