@Zaku You pretty much gave the context in your own answer. Feeling powerless, being ignored, etc. The vandalism is a self-esteem raising response to that.
“Watching Bad TV” is a bit of a value judgement.
For procrastination though, it’s probably a defence mechanism to set aside things that we might feel incapable of doing because of low self esteem, and instead spend time relaxing, doing other activities, or watching bad TV, precisely in order to forget about the thing that we feel like we might not be able to do.
