(Random name) is a glitch item in Pokémon Blue (Japanese) which has a randomly generated name (however there is a tendency for the game to repeat the randomly chosen name pointers). Using BGB's debugger, the name pointer can be tracked by setting a breakpoint to 0:3822 and reading either register pair "de" or "hl".
If this glitch item is used when a 0x50 sub-tile is early enough on the screen (or theoretically if its name pointer is taken where 0x50 exists in the data), it will cause arbitrary code execution at memory address 0xC317.
The random name effect was documented on Glitch City Laboratories Forums by danny.
