dungbag 

orginated from South Armagh (otherwise known as "Bandit County), an insult used my Armagh GAA heads - mainly Liam O' Hare (see GAA-head). A mild offence meaning: stupit, useless, crap etc

when Liam O' Hare or Shane Lennon has just lost in a GAA game/game of table-tennis, they refere to their apponents as "Dungbags", while envious of their apponents victory.
