A rattle snonk is where you have a line of coke with Md at the end of the line then you rip a bong then blow the smoke into a nang, all while your about to finish a wank
Derived from Diablo II: Lord of Destruction, Rattlecage is an armor that looks much like a much higher quality one. When trading, it is quite easy to show the higher quality armor and secretly switch it for Rattlecage without your trading partner knowing.
Rattlecaged means to rip someone off in a deal by giving someone what they think they want, but is actually junk.
When I was trading for my 'nigma, I thought I was getting top notch, but the guy rattlecaged me!
