When a girl texts you “Aaaaah 😩😩😩”, what does it mean?

I’m in a long distance relationship with a girl and we have been flirting over text for a while.We were talking about getting a pair of devices which are just bracelets that send a vibration to partner’s when you tab yours. She is quite busy these days and unable to text be back that often (but she still always respond by next day). I just said I will just touch you (actually means ‘tab the bracelet’) when we get the bracelet when she is busy with her life and can’t reply to my message in time. Her last response was “Aaaaah 😩😩😩” and she stopped responding after sending this. What does this suppose to mean and why did she stop responding? idk if what I told her is that weird or creepy to stop responding instantly…
