Verb - To kill for the purpose of removing said object from the gene pool. The individuals to whom this verb is applied should not, in the speaker's eyes, be allowed to reproduce and pass along their genes. Note: it is a purely humorous word, no one is actually supporting violence upon other human beings.
The word stems from a reference to Charles Darwin who first suggested natural selection as a primary method of evolution.
