Pronunciation spelling of rabbit representing the pronunciation of children and some adults who have trouble saying the English /r/ (the cartoon character Elmer Fudd is a caricature of the latter). Computing sense refers to the ability of rabbits to multiply quickly.
Meanings
(childish, humorous) A rabbit.
A self-replicating computer process that (unlike a virus or worm) does not infect host programs or documents and remains on the local computer rather than spreading across networks of computers.
For example, a hacker might write a quine virus program that generates complete copies of itself as part of its output, a worm virus program that reproduces itself across a network, or a wabbit virus program designed to perpetually duplicate itself, at least until the system crashes. In contrast to the wabbit's slow growth, a fork bomb quickly generates multiple copies itself^([sic]). 2002, Philip E. N.
