Easy drunk
You’re a drunk who gets wasted quick and acts like you’re the king of the bar. It’s basically saying you’re a easy lay but with more drama.
My ex said I was an easy drunk because I took one sip of wine and asked him to dance.
At the party, my cousin called me an easy drunk because I started telling secrets after one drink.
My brother said I was an easy drunk because I took two sips of beer and started arguing with the DJ.
