a wrod to say when something is VERy cool. it fills in the blank;
there are other forms too: spiff, spiffy, spifferific, spiffulous, spiffacious, spifferoo
When you're decorating and have moved so many spiders throughout your day that you simply can't be arsed any more, so instead you cover the spider with so much paint that it becomes part of the property.
For fuck's sake, they just keep crawling back up; it's time for some spider spaffing.
Noun: Where a male ejaculates and then tries to urinate shortly afterwards causing a blockage in his urethra. This often results in pain and inflammation of the penis head as the combination of spaff and urine can not be released.
"I had a great sex with my girlfriend last night but when I went to the toilet afterwards I ran into a major spaffic jam. I was stuck for 20 minutes!"
"I better pee before I masturbate, I don't want another spaffic jam"
