dirtycerda
A "dirtycerda" is when a player dumps a girl while she's pregnant and shows his child off like a new shiny toy.
After dude's been bumpin' on a mattress, spreadin' his seed; he dumps his pregnant lady and comes back after the baby is born to pretend like he's a good dad and shows the baby off to his friends and family. Upon returning the baby to your custody you realize.....That dirtycerda left a bad taste in your mouth. He gave you a dirtycerda.
