A bunch of wasters who are as much if not more to blame for the troubles in Northern Ireland as the IRA. They fought for next to no reason seeing as the legitamet British army were fighting the IRA anyway and target Catholic civilians using the IRA as an excuse. The only difference is that this group although being illeagal and terrorist in nature are favoured and given special treatment by the British.
the UDA were offered £2 million to disarm whereas the IRA were given nothing.

A battle cry. Generally for young black ghetto warriors to yell before they throw their shit down, be it gang related or otherwise. If you are not a black ghetto warrior and happen to hear the call then be warned: millions of thugs will swarm out of every availabe port. Generally, a gallon of koolaid can hold 80 of them for example, while a seedless watermelon will explode with 200 at least.
In Harlem...

White man:"What was that sound?"
Black ghetto warrior:"Uda! Uda uda uda!"
White man:<Dead due to countless bullet wounds.>
