Term for attractive Mexican or Latino girls. Used especially near the US Border where illegal immigration is prevalent. Border Bunnies are viewed as 'easy to get' by their American counterparts due to the perceived notion that Americans are traditionally rich or are interested in being rich and therefore marrying into a American household is the shortcut for a better life.
"Maaaan, that is a fine Border Bunny over there. Hold my drink dude, I'm gonna go try to get me some ass." -Some Random Jock
