The action of sucking up to staff members of a community for no reason whatsoever. A prime example of this behavior can be found on the popular Minecraft server: SchoolRP.
Players can be seen complimenting or being outright creepy towards staff members who probably should not be idolized.
OOC Player A: wow staff member x_z! i really like ur mediocre roleplay!
OOC Player B: dude stop staffsucking he likes kids
A lazy, racist oaf with not much use in society. Usually used in a derogatory manner. The word derives from well-known SchoolRoleplay Admin Customable.
Person A: Hey, man. You ever hear about that one guy, Alex?
Person B: Ew, I know him! He's such a Customable!
