<human>: This is happening as I type. I'm at my girlfriend's house right now and I just took the biggest dump I've had... I've been constipated for a few days. I took my dump about 5 minutes ago (it's 1:30am as I type this).

Little did I know that my gf's mother would be up at this time. She got up and went to use the same washroom... And now I hear her throwing up...

And I KNOW that she knows it was me. What do I do? My girlfriend's asleep right now, so I'm not going to wake her up just to tell her her mom's vomiting in the washroom next door. 

Jesus, her mother must know I did the crime. I feel so bad right now. She's puking and heaving in the washroom. I know it's not from some other thing (such as sickness or w/e.) because I had just seen her a couple hours ago and she was fine. I KNOW she smelled it. It has to be it. She's probably so disgusted of me right now.

Can you summarize the given text in a few sentences?
<bot>: Took a dump late at night at my GF's house. Didn't know her mother would get up and go into the same washroom. Her mom is puking now.
