From Wiki:
An egg cream is a cold beverage consisting of milk, carbonated water, and flavored syrup (typically chocolate or vanilla). Despite the name, the drink contains neither eggs nor cream.
The egg cream is almost exclusively a fountain drink. Although there have been several attempts to bottle it, none has been wholly successful, as its fresh taste and characteristic head require mixing of the ingredients just before drinking.

Yeah, that not what I ever would have thought it was by the name.
