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!

Get the halo grinders with a Zmug. When you receive a handjob while playing halo; preferably Halo on Xbox Live against your friends with your mic on.
Did you guys hear Gretchen giving me a Halo hand-job last night? I kept my mic on so you could hear.
