A sad person that spends all day on their computer watching 4oD rather than watching the programs on channel 4 when they are first on air, instead they them a day later and they insist on doing this; therefore they are permanently behind, causing them to watch the shows on 4oD.
Normal person 1: You wanna ask Dave if wants to come and watch Skins with us tonight?
Normal person 2: Nah he won't bother he's probably watching Peep Show tonight.
Normal Person 1: How?? It's not even on tonight.
Normal Person 2: On 4oD. He's addicted. He told me he watched the whole series of The IT Crowd last night. It's so sad.
Normal Person 1: Jesus...
Normal Person 2: Yeh he's a complete 4oDian.
