Mark is being a hypocrite in this example.
Someone who doesn't practice what they preach.
Someone who claims to hate something they do all the time, but makes lengthy excuses as ti why they do not qualify as that thing.
She's such a hypocrite. She spent the entire class talking about the evils of Capitalism, then durting lunch, she got out her latest-model iPhone & bought tickets for 3 Disney movies from Fandango.
Someone who condemns a thing but does that exact thing themselves. E.g. someone who comments on an Instagram post "Attention seeking behaviour" implying that such behaviour is to be frowned upon, but in so commenting they have invited attention. Such folks might then get into massive long flame threads if picked up on this, inviting yet more attention. In the end they may have scored more attention than the OP.
A: "Attention seeking behaviour"
B: "Dude, you're such a hypocrite"
A: "I'm not a hypocrite, you creep"
B: "Are so - you telling me you posted that comment hoping *nobody* would notice? Hypocrite."
