A word used in Northern Ireland. A hydrid of 'slapper' and 'dog', commonly used to describe a sexually promiscuous but unattractive female. Think fat girl in a mini skirt who presumes her self esteem will rise with the amount of men she sleeps with.
Look at that stupid slapdog trying to pull again.
