"even that blackberry won't fit up your wizard sleeve vagina"<what does it mean?

[nina]

okay. so i went on my friends facebook (were like sisters, she dosent mind. i go on hers, she goes on mine) and someone had written this in her honesty box. i'm guessing its from a guy, since that would be weird coming from a girl....

"even that blackberry won't fit up your wizard sleeve vagina"

so i get they're calling her a whore...."wizard sleeve vagina" means they think shes loose (correct me if i'm wrong)
but i dont get the blackberry part.

so basically, she hasnt done anything with guys in her school, and they dont know what went on outside of that.

and if its really mean i dont want to tell her. she has enough to stress about, and i dont want her to worry about this, too.

so i guess my questions are:
- what does it mean?
- do i tell her?
- why would they call her a whore if shes not?

is the blackberry the fruit or the electronic device?
