Some people...
It's really amazing how some people lack the most basic self awareness. I just played a game of ARAM where our Yi spent the first 3 minutes just standing at spawn, afk-ing. At the end I reminded the team to report, mostly just to let the guy know. He then flies into a rage and starts flaming me, lying about when he actually joined the game, invoking the age old "it's just <insert gamemode>" nonsense, name calling and entirely forgeting the fact that it all started with him not being there... I mean seriously. Is it that hard to admit something that he verifiably did and just take responsibility?
