2. Yadadameentiendes
Yadadameentiendes is used most commonly by the Latin-ghetto community in the Bay Area. The original word is: yadadamean, which means "you know what I mean". The Latinos in the Bay decided they need their own version of the word without straying too far away from the Bay's distinctive lingo, so they came up with yadadameentiendes. They kept "yadada" but changed "mean" to "me entiendes", which means: "you understand me" in Spanish.

So after all that bullshit, yadadameentiendes means"

7. sammy the bull
See: Grass def.3, Snitch def.1, Rat def.1

Sammy the Bull is like a nickname for someone who snitches, usually getting the accused into some serious form of trouble due to their grassing. Comes from Salvatore 'Sammy the Bull' Gravano, who grassed on John Gotti.

Mostly used to describe those who engage in illegal activity themselves, and then grass about their so called friends, so that they themselves don't get into any trouble.
"And the Sammy the Bull award goes to, Fat Joe." - Tony Yayo (Tattle Teller lyrics)
