Definitely a boy

He's a boy...now what was mooooore gender confusing was the earlier naruto episodes when naruto met/fought Haku...remember he was Zazubas right hand man...that guy even dressed like a girl more then a guy. i thought he was a girl for the longest time until he told Naruto hes a guy.

um... in the past at narutokun.com that deidara is girl then in shippuden deidara is a boy. isn't it?

hes a guy and about that naruto haku thing i was soo inbarassed cuz i said haku was cute i thought it was a girl im not gay!!!

deidara's a man.

but that would be funny if you did that though. hahaha!

hes a boy and all u do is have to see how he pees
