And I'm all up, all up, all up in the bank with the funny face

from Kanye West (Ft. Bon Iver, Jay Z, Nicki Minaj & Rick Ross) – Monster Lyrics on Rap Genius

Meaning

People often criticize Nicki Minaj for the faces she makes in music videos — similarly, she is laughing all the way to the bank. An example of a face she might give a teller:

Bank robbers often wear masks while doing robberies in order to conceal their identities. The masks can have funny faces, like the mask of Richard Nixon’s face, which is used by bank robbers in many movies/shows.

This line always is also reminiscent of the opening scene of The Dark Knight. Jay Z quotes the movie in the next song, so it was definitely on their minds at least a little.
