Boogie's Boys seem to be named after parts of a gun.
Oogie Boogie's henchmen, also known as Boogie's Boys, are named Lock, Shock, and Barrel.
This is likely a pun on the phrase "lock, stock, and barrel," which informally refers to a complete set of something, but the phrase itself is also a reference to various parts of a gun.
As the three characters are never seen without each other, and work together to cause chaos, their names suit them well.
