Jenkins should ignore wip-prefixed branches

When I work on crazy stuff that breaks a lot of stuff for a long time. I still would like to be able to push it to our repo without wasting Jenkins’ resources. Could we settle on a wip/-prefix for branch names, that means that Jenkins will ignore it completely?
