look up any word, like rimming:
 
1.
As above: shoooting up heoroin or the like. Called so because a session will leave a dark linear mark (known as a "track") at the site of the affected vein. Harcore users will tend to have multiple sites of injection and will locate, or "spot" an optimum vein - one with minimal "tracks" and discomfort or infection. A hit can be analogous to the impactof a locomotive or train.
That's how I figure it anyway.
Watch the damn movie. It rocks. try reading the book - the narration is spelled with a scotish accent all the way through.

Observing trains and logging the numbers. Generally involves standing around in bad weather, watching the tracks. A British hobby.
Oi! Me and Tommy are going to head down to the station and do a bit of trainspotting! It looks a bit rainy, so bring an anorak!

Great British film about people taking heroin and their struggle to get off it. Contains best quote ever. Was also filmed outside of my school who were a bit pissed off once they realised it was about taking drugs.
Trainspotting rules. Begbie is a legend.

trainspotting:

v: The act of staring over a DJ's shoulder to see what records he's spinning..

Originated from the British phenomenon of train geeks waiting on train platforms, notebooks in hand, recording the types and numbers of trains coming into the station.

Also the name of a famous book by Irvine Welsh in 1993, later made into a much more famous movie in 1996 by the same name. The word at the time referred to dance music geek culture, but was about the wasting of Scottish heroin addicts.
"I went to the club last night to hit on this bad-ass DJ chick, but the records she brought were amazing, so I just sat near her at the decks trainspotting them all night!"

An incredible movie that will blow your mind. I'm not allowed to put the entire quote into the "example", so I'll put the first half into the definition section. Too many "choose"s, apparently.



Choose Life. Choose a job. Choose a career. Choose a family. Choose a fucking big television, choose washing machines, cars, compact disc players and electrical tin openers. Choose good health, low cholesterol, and dental insurance. Choose fixed interest mortage repayments. Choose a starter home. Choose your friends. Choose leisurewear and matching luggage. Choose a three-piece suite on hire purchase in a range of fucking fabrics.
Choose DIY and wondering who the fuck you are on a Sunday morning. Choose sitting on that couch watching mind-numbing, spirit-crushing game shows, stuffing fucking junk food into your mouth. Choose rotting away at the end of it all, pishing your last in a miserable home, nothing more than an embarrassment to the selfish, fucked up brats you spawned to replace yourself.
Choose your future. Choose life. …But why would I want to do a thing like that? I chose not to choose life: I chose something else. And the reasons? There are no reasons. Who need reasons when you've got heroin?

Trainspotting is a term or reference used for people that have probably too much spare time on their hands, and have the ability to draw on useless information that seems relevant at the time.

runnig time? - 116 min.
director? - lewis gilbert
screen writer? - ian fleming
fuck off, he never wrote any of 'em - ok, so who wrote it then?
you can look it up. how do you feel since you came off the smack? speaking for my self, i am bored. - who wrote it?

roald dahl. - roald dahl?
>this is a conversation between the characters "renton" and "sick boy" from the movie trainspotting, it's a deleted scene<

jerry seinfeld has also a very impressive knowledge about useless information.

v. The act of watching a DJ work with turntables and vinyl. This can be done to see how the DJ scratches, beatmatches or in any other way show off for the crowd.

Guy 1) Look at that DJ spin!
