I live by a simple code
I love the concept of the word "boop!"
It defines all the champions I play. Veigar Leona Morgana Karthus Mundo Taric Zilean (the single boopiest of them all)
The term is used to express the use of a ability. If a ability make contact you say in /all chat "boop!" It's more for fun and it's how I got my summoner name. People see it and they know what to expect. The term boop can also be applied if you do something to your team. In this case if you're lets say Soraka. I pretty much call out boop in my skype calls with friends as I heal them. All you ever hear is boop from them when doing something afterwards.
The idea is to have fun, pure and simple.
Find that champion who you think has maximum boop potential AND PLAY THE SWEET MAFOOBIES OUT OF IT!
