What is a lash egg?

There's no known object or concept officially called a "lash egg." The term is likely a creative descriptor or a misunderstanding. It could potentially refer to a few things depending on context:

• A descriptive term for a large amount of eyelashes: Someone might use "lash egg" informally to describe a clump of eyelashes, perhaps shed ones collected together, similar to how "hairball" refers to a clump of fur. This is entirely figurative.

• A marketing term for a lash product: A company might coin the term "lash egg" for a specific lash curler, serum, or other product packaging. It's unusual, but not unheard of in the beauty industry's sometimes whimsical naming conventions.

• A misspelling or mishearing: It's possible the term is a typo or a misremembered phrase. Perhaps it's related to a different term within the beauty or eyelash extension industry.

Without further context or a specific source, it's impossible to give a definitive meaning for "lash egg."
