John Thomas Cockney Rhyming Slang
John Thomas is Cockney rhyming slang for penis
In literature
The phrase is spoken at least four times by the Mellors character, in Lady Chatterley’s Lover by DH Lawrence. At the time this was considered obscene and the book was subject to an obscenity trial. But today it is the mildest of euphemisms for the penis.
