Would you understand me if I told you that “…we be geese, man!” You might if you understand that geese travel long distances and in large numbers. Therefore, to “be geese” means to travel, probably greater rather than shorter distance, and quite possibly with companions. I learned this little snippet of word play via the Rap Dictionary. You can browse through the adjectives (crunk), the nouns (rat pack), the places (killa city), and more. Yo, dawg.
