When you steal the kill with a Soraka auto-attack

no one expects the Banana

That's where her joke "No one expects the banana" comes from. It's been a gag for years.

I am. It's one of the slowest autos in the game besides Karthus. So when you just want your assist and take the whole kill, your adc throws a piss fit like you did it on purpose yo. Like, "Yes, that was a banana, okay? No one expects the banana, not even me!"
