In the USA money laundering is called smurfing.

(In the original series of the Smurfs, the little blue characters tended to replace a verb with some form of the word “smurf”; e.g. “I feel like smurfing some bread,” instead of, “I feel like eating some bread”. In the USA the DEA started using the word as a code for Structuring, the act of making money transfers repeatedly in small amounts to avoid suspicion.)
