look up any word, like twoosh:
 
1.
When irish teenagers are underage and have nothing less to do they go knacker drinking this is where they buy (or some one who is over 18 buys for them) cheap alcohol (usually dutch gold or vokda) and drink it in woods or the side of the street parks are also popular.. its usually pissing rain and you go home feeling like shit and wet... but it was a night out and you dont feel the wet cause you are so drunk.. all is well until some night the gaurds catch you and you are brought home in the back of the cop car or your stomach gets pumped...
Girl 1 says to girl 2 : you goin drinkin tonight?
Girl 2 answers: yeah i will get a few cans and meet ya up the park around six... i will tell my ma im at your house ok?
Girl 1: no problem see ya then

2.
When someone over 18 or someone that looks over 18 gets loads of cheap drink for underage irish teenagers, which they drink in the middle of no where until they don't remember what they did and go home either absolutely hammered(much to the dismay of their parents?) or in an ambulance(much to the dismay of their liver).

The act of consuming alocoholic beverages outdoors, often in a park or field, and preferably near a waterway, often engaged in my youths not old enough or rich enough to drink in bars.
"Me and the lads was knacker drinking down the valley with the girls on Sa'urday. Was fookin lashed, but than the Guards came and we had to leg it and I lost three tins of Bulmers.'
