Malphite debuted in League of Legends in 2009 as a hulking shard of living rock, best known for Unstoppable Force, his game-changing dash and knock-up ultimate. A7a is a common Egyptian Arabic exclamation used for shock, annoyance, or disbelief, roughly like saying oh come on. Arabic-speaking players merged the two into a quick reaction clip for huge Malphite plays and disastrous engages. The pairing spread through soundboards and short gaming edits because the shout instantly explains the emotion while the champion name gives League players the full context.
