In the mafia for example they would say something like,
"The dishes are done and the kids are in bed" to imply to a hierarchy or an associate in a public place that the order was successfully carried out, such as the transporting of drugs, blowing something up or murdering someone.
Or: I'll bring the party "supplies" by your house around 10. (supplies being alcohol w/o being directly stated)
jack: i was implying something else so others wouldn't know what i was really referring to. it's called the quotation mark effect.
