Someone else said Scarecrow for Fiddlesticks, that is a commonly used one you should put in the list.
Zilean I hear called Santa sometimes.
RoA = Rod of Ages, balanced caster item that scales with time
gp5 = Gold per Five, for example Avarice Blade, Heart of Gold, Greed mastery.
IE = Infinity Edge, toptier item for damage and crit
I would add the term: "re" - returned; enemy returns after an MIA (missing) call
And I agree with also adding "Clown" (shaco)
Blitzcrank = gayhand
Karthus = Kel'Thuzad (Warcraft 3)
