Someone who is "an ice cream" is ........?

[soulstar11]

Does any one know the term "ice-cream" to decribe someone?
Have read it a few times in a Derek Raymond novel. At one point he is describing a (dead) tramp, so I thought it might be a derogatory term for vagrants or corpses, but he later describes a living character as the same.
I imagine it may be a london term, but it's not form of rhyming slang I'm aware of.
Any ideas?
Cheers

Thanks soulstar11 for asking this question and thanks to Panic Button and shaneystar2 for answering it as "ice cream" is a term that I wasnt familiar with and Martina Cole uses it a lot in her books and its been driving me mad trying to think what it could mean now having seen your answers it should have been fairly simple to work out doh!
