Rock stacker is a racial slur against Arabic people. It is insinuating that they are a primitive people that haven't advanced out of the middle ages. I hear it at least once per week. I am surprised it hasn't already been submitted.
I saw a bunch of rock stackers talking rock stacker at the Quik-E-Mart so I turned off my cell phone so I wouldn't detonate any I.E.D's they had.

Get the ROCK STACKER mug.
Any worthless person with a total lack of consideration for others. They include homeless people, ultra-hippie tree huggers, ultra-religious extremists, stupid people, cyclists who attack cars, car drivers who ignore cyclists, a self-entitled child, a self-entitled child's parent who caused his or her precious little snowflake to act like an ass, others like them.
"Could you turn off your cell phone and wireless router? They give me headaches."

"No they don't, what are you talking about?"

"If you don't turn them off, I'll sue you!"

"Fucking rock stacker..."

Hippie, wannabe hippies and losers new to the outdoors that stack rocks in unnatural piles. This is done for a few different reasons. One is simply to say, "I was here." Another reason is just to claim a prominent spot for their Rock stack before some other Rock stacker makes their own stack on that spot. The third and original purpose of the Rock stacks was to guide hikers and keep them on a trail, any unatraul sign would serve this purpose. Rock stacking amateur dorks do not know or care about the origins of Rock stacks, they just want to make one on every virgin spot they see so they can photograph them and post it on Facebook. Real hikers do not have the time or inclination to unnecessarily stack rocks, they are driven by he challenge of hiking and not making cute piles of rocks on every ledge they see.
"I wish these damn Rock stackers would stay home instead of fucking up the trails!"
"Damn Rock stackers shared all of our supplies but none of their own, typical!"
