A social condition describing a person's need to display their distaste or dislike for certain people, without naming any names, on their Twitter or Facebook status.
Often intended to elicit comments from supportive friends, and infuriate or annoy others.
Carl: "Why did Jen put 'is tired of playing games with all these children - you know who you are' on her status?!"
Bill: "Because man, she's got a fierce case of SAS (Status Aggressive Syndrome)"
Aggressive Power Chillen or "APC", is the action of actively seeking to max out one's chilling. eg: if you are regular chilling, sitting in a chair, you can transcend to aggressive power chilling by kicking feet up, slouching to the highest degree possible, and smoking/drinking whatever is around you.
When in a church atmosphere, (typically in a youth group or bible study,) the pastor or leader asks for someone to pray, read, or a volunteer to help; they are passive-aggressively asking a specific person or persons. Usually with a stare right at someone when they are "asking the group".
Dude, when pastor asked for a volunteer to help pass out snacks, he pastor-aggressively stared right at me, so I HAD to do it.
