Rattlejack: is the ultimate act of doing someone wrong that is close to you, extreme form of being "jacked". When you go out of your way to set up a friend to fail or rat them out to a significant other or acquaintance.
Some examples include texting a friends girlfriend asking her what she is wearing to a wedding that her boyfriend did not tell her about and did not intend on bringing her to or having a bad night out with another couple and before you even end the evening the other couple is getting texts about what a bad time was had by all. The final version of Rattlejacking is self inflicted. An example of self inflicted Rattlejacking would be waking up the morning after a heavy night of drinking to find your new SUV mangled and not remembering how or when it happened but you know you were driving.
