A non-existant ten pound note, which is used for the purpose of online wagers or bets with others; where there is no intention of money changing hands regardless of the outcome.

The phrase originates from the online UK motorbike forum 'Visordown', specifically a user called 'Soapy' known for making bets with no intention paying anything.

Soapy made a £10 bet with another VD'er over something or other, turns out that the other VD'er won the bet but Soapy never coughed up.

A Soapy Tenner is a £10 note that you will never actually see but still gives a modicum of weight to your argument by it's very presence.

From the example given we can see that even though the chance of the tomorrow being sunny is quite high, there is a possibility that it won't. You should therefore NOT risk your real tenner, but use your Soapy Tenner which has the built in option of non-payment.

The origin of the Soapy Tenner is a regular forum user at www.visordown.com you would regularly bet £10 on the outcome of various discussion and never pay.

Far from being the work of any one individual, the phrase Soapy Tenner has existed since the agricultural revolution, when Jethrow Tull - fresh from inventing either the seed drill or the spinning jenny - staggered into a local house of ill repute, and demanded a 'soapy titwank' to wash the filth that clung to his nether regions.

The quick witted whore replied that she'd want a 'soapy tenner' before she let him ream her jubblies with his filthy love-wand, and Tull agreed.

after shooting a sticky load into her hair, he proceeded to knee her in the crotch and run off without paying. The phrase 'Soapy Tenner' came to mean a tenner you're never likely to see.
I bet you a soapy tenner Jethrow Tull didn't invent the spinning jenny, fool.
