The name of a dog with Mexican roots and a drug cartels' background. The word is derived from the word 'sancho' in Spanish. The direct meaning is 'little lady stealer'. Sanchito can be found either holed up in blankets or prancing throughout the neighborhood.
"Tell Sanchito that if he knows what is good for him, / He best go run and hide" (Santeria -- Sublime)
Similar to a dirty sanchez, the difference being that the man would stick his fingers in the woman's vaginal opening while she is on her period, and proceed to smear the residue across her upper lip.
"So, it' s that time of the month, hon? You know what that means!"
"Not the dirty snachita again!"
