Deidara: MasterBator

Imagine trying to wipe your ass with those hands and the toilet paper rips through.

I have a question.

How is that useful? Tongues in your hands, how are they used in being a ninja?

You'll be able to give someone a wet bitch-slap, but thats the full extent of usefulness.

If he's ever lonely, he can place his palms together and make out with himself.

He uses them to mold his clay bombs. He also has one on his chest, that, when fed clay, turns him into a suicide bomber.

....how would he practice that? how would you learn that?

born with it? mouth demon? animators have shit happen without even thinking of why?

probably a bloodline

its easy to assume its a bloodline trait of a deceased clan such as the sharingan of the uchiha (though that was explained in depth recently)

pro-tip: dont bash stuff when u already made it obvious that you do not follow it, that being said most animes or shows in general do not explain everything

I followed it all the way up to the time jump.... and I didn't bash, I tried giving helpful suggestions....

Have you ever even read Naruto?
