Why did she act like this?

Why was she asking for my Snapchat multiple times. this girl who says hi to me left her table of friends at lunch and came up to my table where I was sitting alone. we chatted to get to know eachother better then she asked me if I had a Snapchat. I said yea but I don’t use it like that. she goes use the same excuse I said but she said she jokingly creep on people stories. I’m like ok then she asked for it again I said no. she said please 5 times after I said no 5 times. why did she do it?
