Saturday Night Live 

In the "hobbyist" community, describes an escort who is or appears to be "not ready for prime time", or under 18. Usually given as a warning on online escort review boards and sometimes shortened to "SNL". Sometimes the board autocorrects the typed word "underage" to Saturday Night Live to throw off LE (Law Enforcement).

"Be careful of this one; she's very pretty of course but definitely looks Saturday Night Live."
