Chocolate button eyes are beautiful deep brown eyes with thick dark lashes. If you need a visual take a look at Joseph Quinn, a handsome, kind, phenomenal actor.
when your girlfriend is asleep, you put cadbury's chocolate buttons in her ass crack, as the night wears on the chocolate buttons melt, thus upon awakening the poor bint thinks she's shat herself during the night
"oh my god, I think I've had an accident during the night.......i'm so embarrased"
"hahahahahahaha, you just got chocolate buttoned, bitch!!!!!"
