:wank: /wangk/ [Columbia University: prob. by mutation from
Commonwealth slang v. `wank', to masturbate] n.,v. Used much as
{hack} is elsewhere, as a noun denoting a clever technique or
person or the result of such cleverness. May describe (negatively)
the act of hacking for hacking's sake ("Quit wanking, let's go get
supper!") or (more positively) a {wizard}. Adj. `wanky'
describes something particularly clever (a person, program, or
algorithm). Conversations can also get wanky when there are too
many wanks involved. This excess wankiness is signalled by an
overload of the `wankometer' (compare {bogometer}). When the
wankometer overloads, the conversation's subject must be changed,
or all non-wanks will leave. Compare `neep-neeping' (under
{neep-neep}). Usage: U.S. only. In Britain and the Commonwealth
this word is *extremely* rude and is best avoided unless one
intends to give offense.
