After a certain point of inebriation, one begins to say things that sound good in their current mental state, any of which said sober would sound utterly retarded.
Person A-"You know I've always loved you."
Person B-"That's just Drunk Sincerity, go sleep it off."
The innate ability to express the truth through words and get in trouble immediately after.
I told the girlfriend that I would like to get to know her better before I can truly and honestly respond in kind to her "I love you." She got upset, got up, dressed up and left. That was relationship sincericide.
The most mysterious girls you'll ever meet. It will seem like she's into you at first, but sooner or later you'll realize she never thought of you like that in the first place. She is very kind and beautiful, and loyal too. It's always easy to fall for Suneri, but it's rare for her to love anyone, so don't get your hopes up.
boy/girl 1: hey did you see Suneri?
boy/girl 2: yeah omg isn't she stunning?
boy/girl 1: yeah, but she rejected me last night :(
