burritos are called burritos because in the days when the border wasnt patrolled much between the US and good ol TJ, the tijuanan men would come do labor in southern california. they had to get up early in the morning, so their wives would mix all of their breakfast and wrap it in a tortilla, a mexican to-go box, if you will. the men would eat the food whilst riding their burros, or donkeys, into america. hence, burritos (little burros).
