In this photo you can clearly see both of Kirby’s hands!
In other words…
There is NO WAY Kirby could have taken a selfie!!
Wikipedia and Urban Dictionary both define a “selfie” as a photo of someone, taken by themselves. Usually from arm length, or through a mirror. So even if Kirby did ask someone else to take the picture for him…
It still wouldn’t count as a selfie!
You are ignoring the fact that most cameras have a fancy option to use a timer that takes the picture when the taker activates it.
Kirby could’ve perfectly used this option to take the picture, which even in your urban dictionary definition would still count as a selfie.
