Thread: Is this Russian Slang?

Ггггггг гггггг)))))
Люблю тебя)))

I'm just starting to learn Russian. Sometimes my girlfriend puts something unusual in an email like:

Ggggggg gggggg)))))
Love you)))

What is she expressing here? "Ggggggg gggggg)))))"? Is this a Russian slang expression? If so, what does it express?

Thanks for any help : )
