Short for 'Arbitrary' - this acronym is used more commonly where the context of the word implies the likes of the target object/subject being 'random', 'strange', 'unusual', etc...
What an arb picture - looks like the guy's head is out of proportion with the rest of his body! And what's up with that pink porche in the background? Must be a photoshop.

Short for arbitrary person not worthy of mention; when referencing the name of the person/thing is unnecessary.
"Remember that arb dancing with Danielle last night?!"

"Tony always talks to the most arb skos I've ever seen!"

short for Protoss Arbiter from the PC game, StarCraft. The flying vessels provide invisibility to surrounding friendly units. They can stasis units to protect them from any and all damage, and can use recall to teleoprt units anywhere on the map.
Holy crap dude, that Arb just recalled 8 Reavers into my minerals.
