My sister lying about having a boyfriend?

infernoskies
She's hardworking, smart, and good looking but this year she was put into a class with only guys.
They make fun of her and annoy her and she happened to be so annoyed with them that she lied about having a boyfriend. Apparently she said she had a French boyfriend. The reason was because she thought it would maybe work because my cousin is French and pretty good-looking.

Yeah it might be a joke but they took it really seriously.

The question is, what should I do? How can I tell her to defend herself in another way and how?
Also have you ever been in a situation like this?
She's also a senior and I'm only a freshman in high school! Do you think that this is joke to her? I mean she could get a boyfriend if she wanted one trust me but why would she lie?

Poll!
Do you think this is okay if it didn't get out of hand?
