A colloquial expression that refers to trivial, unnecessary, or small-scale mischief, drama, or antics that are carried out with the intent of annoying, inconveniencing, or provoking others. These acts are often spiteful or mean-spirited but lack any significant malice or serious consequences. They are typically perpetuated out of boredom, a desire for attention, or as a means of asserting dominance in a playful or passive-aggressive manner.
"I can't believe she spent the entire meeting doodling unflattering cartoons of the boss. That's some high-level petty fuckery right there."
