Behold a new verb...
to scupper
(said SKUHP-er)
1. Informal. to prevent from happening or succeeding; ruin; wreck
2. Military. to overwhelm; surprise and destroy, disable, or massacre.
It does have a noun but it is boring and something to do with drains I believe, and in navel slang it is an offensive way of describing a woman so we shall ignore these. I must admit even so it isn't such a positive word as a verb (very ironic I did pick this seeing as today while I am writing this it is clear, sunny and extremely pool-worthy and I am sitting at the computer in togs) but it does give a certain nuance that may be needed someplace?
