Any combination of narcotics mixed for insufflation.
I've got some ket left, let's add it to the coke and mandy and make some Neapolitan Lines.
A useful umbrella term describing the Circle, Hammersmith & City and Metropolitan lines' shared route between Baker Street and Aldgate. On London Underground maps these lines are individually colour-coded yellow, pink and magenta. When viewed side-by-side the lines resemble Neapolitan ice cream, albeit with the Metropolitan line's dark magenta replacing Neapolitan ice cream's chocolate brown.
Example 1: "How do I get from Liverpool Street to Farringdon?" "Any of the Neapolitan lines will do" Example 2: "What lines pass through Baker Street?" "The Bakerloo, Jubilee and Neapolitan lines"
