look up any word, like donkey punch:

A walking wank is for the bored gentleman who is in favour of getting naked in ones home and choosing to masturbate whilst travelling from one room to another.

This is an activity which is not always understood, but however seems to be attracting attention from various specialist websites.

Its not known how many men take part in this but it is suspected that it is in the high numbers. it is a solo activity that is usually done in the absence of a partner who, for example, is away from home or at work etc...
It is reported to give the gentleman a great sense of freedom without having to go the whole way towards perversion and lewd sexual acts...

it is unknown whether this is a gateway practise that may lead to a more serious deviant behaviour which is known as a WWW (walking Window Wank)
"great, she's away, time to stick on the nina simone tunes and have a walking wank"

or

" i just walked in on him naked and prancing about laughing, he told me he was feeling great and enjoying a walking wank"
