<human>: Before my girlfriend and I got together (a year and a half ago) and were getting to know each other, she asked me what my background was. I tried to impress her while being as high as a kite, so I told her I was part Jamaican and part Irish. The truth is that I'm just Jamaican [(selfie!)] I told her that my accent only comes out when I'm drunk and she ate it all up. As time went on, I maintained that I was indeed a proud Irishman but I never gave her any further information. Every time that the topic came up over the past year, I would reconfirm that I was in fact Irish and that one day I'll treat her to my Irish accent, but not right now because I'm "too tired".

Today she brought it up again and I decided it was time to come clean. I confessed immediately. I thought that she'd be mad as hell but she just laughed her ass off and told me to post it on Reddit.

Can you give me the gist of the text in a nutshell?
<bot>: Expected to get rekt for blatantly lying about my background. Laughed her ass off instead and told me to post the story on reddit.
