Seiso

A person who is pure in body and mind. Usually refers to a virgin who doesn't have any sexual experience or knowledge on basic human reproduction. Depending on who you ask, being seiso can also include things like staying away from alcohol, smoking, and drugs as well.

example 1. Danny Phantom : man, that guy is way too seiso! they don't even know what smoking means!

example 2. Elia Stellaria : hey guys who wants to get touched? what, who said that? that wasn't me! I'm seiso after all!
