look up any word, like dirty sanchez:
 
1.
n. pseu-do-mex-i-cism

1. To pretend to be Mexican.
2. To suggest or imply you are of Mexican decent when, in fact, you are not.

From the words pseudo (meaning false or counterfeit; fake) and Mexican (meaning a native or inhabitant of Mexico).
Malinowski is of Jewish and Polish origin, therefore if someone of this name was light skinned with blonde hair, claiming to be Mexican would be pseudo-mexicism.
