Recently I've come upon a shit test I haven't seen as frequently in the past and I'm trying to analyze what this means.

Last night I was chatting up with a girl I had seen around previously and I wanted her contact info, so I asked for her snapchat after a quick convo. She gave it up easily.

Then she says "Don't get mad if I don't reply to your messages" adding on "Sometimes people get mad at me when I don't respond", after she had given me her snapchat. I thought this was a weird response so I flipped the pressure and said "Who said I was going to message you?" jokingly, which led her to not know what to say.

What kind of a shit test is this and did I do the right thing? This is not the first time I've heard something along these lines but it seemed like an odd thing to say. Please be aware I have no stake in this girl/ oneitis, but this was just a good example of this shit test.

Thanks in advance.
