A fanciful term describing excited homosexual intercourse involving satsuma peelings, empty coke cans, and earl grey tea bags of the twinings® variety. (During the winter months in northern European countries, it is also considered quite kinky to engage in a razzle whilst listening to Dvorak's 8th symphony, movement IV. The flute solo is considered the climax of the experience and should be cherished for months thereafter.)
One gay man to another non-gay friend:
"Oh yes, Kevin and I had quite a razzle the other day."
"Say no more, say no more."
