A berry (usually a strawberry due to its size) dipped flamboyantly in chocolate, served with powdered sugar and with the finesse that could only be provided by someone who frequently takes the male phallus up his rectum.
'Hey man, how good were those Gayberries at the brunch this morning!'
'Shit man, I only got to eat one Gayberry, it tasted like the first time I heard the beatles'
'Yo Chad, I wish I was gay so my chocolate strawberries tasted like that, my wife says mine taste like shit'
