Incestuous, boxing, sovereign ring wearing, tracksuited shaven headed scumbags. Girls wear bellytops (Even if they're 15 stone), guys are small, jewelry and violence are rampant. Enjoy having children with sisters, looking at you with squinty eyes and scaring people. In many places refers to SCUMBAGS in general, and good travellers are not covered by the word - depening where you're from.

A knacker is your general scumbag from Ireland. Males wear caps balanced at an upright angle on their head, at least 5 gold rings and sovereigns on each hand, large gold chains around their necks, matching tracksuits or shirt under Satellite Sports stripey jumper. Adidas, puma, nike or burberry clothing essential to fit crowd. Females wear: Maternity clothes, knacker hoops (large earings that reach from earlobe to shoulder) Prams, belly tops and tracksuits with their knackery fat hanging off the side.

All knackers enjoy "Bockin' da head o' ya, gear, yolks, dope. hub caps, robbing, thieving, lying, transit vans, horses, lifestyle sports, penneys clothes, supermacs, macdonalds, cinemas, crappy civics and puntos. Fighting, rolling up their sleeves.

God I hate knackers.

They also can't read or write, and try to rip you off by selling u a microwaved eight instead of a decent quarter.

They can't speak either.

Unpolictically correct name for scumbags. Mainly used in Ireland it describes the gaudy, track suit wearing, urban dwellers who hang out in gangs looking for people to beat up for no reason (male & female), getting drunk in public places (male & female) and getting pregant at age 13 (usually only the females).
You can recognise them by the white baggy tracksuit, white and neon trainers, burberry cap and their refusal to pronounce the end of their words.

Due to the connection of the word "knacker" to the traveling community, the slightly more PC term "Skanger" is often used.

Members of the Irish Traveling community with nothing better to do than steal hub caps off cars, wear tattered clothing or pointlessly beat businesses signs with sticks.
Popular knacker names include Francie and John-Joe.

Another meaning of the term "Knacker" can roughly be equated with the English term Ned, ie, a person who wears nothing but Nike, Adidas or Puma gear, stands on the corner of the local Mac Donalds all evening trying to intimadate young children who walk by.

Generaly however, all members of both Knacker sub-divisions display complete ignorance of all civilisied culture.
