a jumping bean is a person of non-latino heritage who assumes a latino accent when saying words in spanish. I have to clarify that one can say the proper word without assuming the accent.
I saw mr. hernandez (pronounced "Hairnondayz" with thick, sent-up latino accent) on the street today.
The nick name for a person who portrays the qualities of a "bean bag." If you ever see Barry Barry Bean Bag be sure not to drop the soap. Also known as "Barry Barry Bullfrog."
Person 1: "Hey who is that making out with that dude."
Person 2: "Oh shit dude, thats BarryBarry Bean Bag."
