a twin
A twin is when your friend slips you a pill in your drink without you knowing, and it’s usually some stupid pill like mdma.
My twin slipped me a pill in my soda, and I got so high I danced in the grocery store.
My friend thought I was drunk, but I just had my twin slip me a pill.
My twin put mdma in my drink, and I didn’t even notice until I was screaming at the moon.
