Spiff

A bonus payment for closing a sale or making a deal go through. Unlike commission, spiff is paid out directly in cash, from the manager/owner/whatever to the salesperson, pretty much immediately upon the completion of the sale.

You just sold a $5000 diamond ring? You're gonna get some sweet spiff on that!

Spiffing

A very dated word used by the upper-class British, and Americans that can't do impressions for shit.
Can be used for comedic value.

Usually found in sentences containing the terms; "Jolly good" "Old chap/chum" "Tea" "Wot wot" "I say" and "Earl grey"

I say, old chum. Would you like to come to Buckingham palace and share a spiffing pot of the old earl Grey, wot?
