A term most popular in Gen Z and onwards, “sneaky link” is a combination of the verb to link (which means to meet up/hang out) and sneaky (which means to be discreet).
Because of the nature of how these two terms interact, the compound noun “sneaky link” is most commonly used to refer to a hookup, though it can also be used to describe a friends-with-benefits relationship.
Friend 1: What’s good witchu bruh, I know you tryna smoke tonight.
Friend 2: Ayum you know I would, but I got a sneaky link tonight, you feel me?
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"
