I had to look up whatever that is...
Same here.
Mordecai is more conscientious, mature, and moral about his actions, but he tends to go along with Rigby's antics as a result of rivalry. He's also prone to jealousy, often towards Rigby, causing him to act angrily and recklessly; he once killed Rigby, but later wished him back to life.
Rigby is eccentric, immature, and extremely mischievous, which puts him at odds with Mordecai at times. Rigby lives mostly for self-gratification, which he sometimes achieves through selfish acts of lying (Rigby has mostly lied, most lies shown in "Diary")or cheating; but consequentially, Rigby has a bad habit of getting himself and other people in trouble. His willingness to lie and/or cheat when the opportunity to do so arises suggests Rigby has questionable moral character.
They do sound a lot like us.
