Sneaquila 

A sneaky shot of tequila that nobody knows about.

“Hey Jeff, want a shot of tequila?”

“I don’t want Evelyn to see, can we do a sneaquila instead?”

sneakquel 

A "further adventures of" production dat is quietly/surreptitiously released instead of being openly advertised/hyped, possibly because of said film's boring nature, unpopular political views, copyright issues, etc.

Creating a sneakquel to a well-known Hollywood masterpiece might indeed keep you out of legal trouble, save you from public ridicule/outrage, and so on, but it might also take a while for said celluloid-based work to become known to da general viewing-audience.
