What is 9 Thing?
the 9 thing, is the moment at which a programme starts on E4, and a large number of 16-25 year olds tune in.
Also, a 9 thinger, somebody who tunes in at said time, to said channel.
The O.C, Smallville, Invasion blah blah
"What are you doing tonight?"
"Its Monday, E4 of course"
"Ah, so your a 9 thinger"
