One who gets overly emotional and overrun with feelings of love when drunk.
This person is otherwise contained and functional, but get some alcohol in them and suddenly they are all tears of happiness and thankfulness that they have "friends like you."
Beer Queer: I am -so- thankful to have you guys in my life *sob* you are -always- there for me when I need you.
I love you guys so, so, so much! *sob.
Friend: Dude. Get away from me. Stop being such a beer queer.
