Someone who stays up late to grind halo with the boys. The "with a Z" is referring to the s in grinders, so instead of grinders it is grinderZ. By putting a z at the end, it shows true dedication to the grind.
Grinder 1 : Calling all halo grinders with a z, let's all hop on halo tonight.
Grinder 2: Sure! Cortana is so hot!
