Having the same South African values, a Kruger is a poor version of a Krugerrand. See Urban Dictionary definition of Krugerrand.
The same as a
Cougar in these states of America, a Kruger too, will prowl the singles bar scene in search of prey..., which is young men. If immigrated to
U.S.A., a Kruger can usually be identified by a
thick German accent. Hence, the given name, "Greta Garbo Kruger."
