breeder

1. (cellular automata) A pattern that exhibits quadratic growth by generating multiple copies of a secondary pattern, each of which then generates multiple copies of a tertiary pattern.Examples: "I was wondering if anyone out there could mail me a base for MIT's 'breeder' - the one with 8? puffer trains forming glider-guns. I've seen in in^([sic]) a few books but can't seem to get it working ..."; "I later implemented an improved version of the algorithms on an Atari STe, this time the goal was to run the breeder, which it did at 2 gen/sec at the stage when the first glider gun has been assembled."; "A glider-emitting breeder pattern can probably also be constructed in this rule, which would out-radiate any chaotic pattern by a considerable margin."

2. (slang, derogatory) A person who has had or who is capable of having children; a person who is focussed on the rearing of their own children.Examples: "The number of souls in this kingdom being usually reckoned one million and a half, of these I calculate there may be about two hundred thousand couple whose wives are breeders; from which number I subtract thirty thousand couples who are able to maintain their own children, although I apprehend there cannot be so many, under the present distresses of the kingdom; but this being granted, there will remain an hundred and seventy thousand breeders."derogatoryslang

3. (LGBTQ slang, derogatory) A heterosexual person; one whose sexual intercourse can lead to breeding.Examples: "Since the breeders started coming here, you can never tell who likes cock."; "When visiting gay friends but wishing to avoid any heterosexual passersby or dinner guests of said friends, one can always call ahead and inquire, "Are there breeders in your home?""; "“Hey… what does a breeder know?” Michael grinned. “Where did you learn that word?” […]“One of the guys at Perry's,” replied Brian. “He said that's what the faggots call us.”"derogatory
