How to get yourself ostracized in hall?

1. Blast music day and night without any sense of time.
2. Join comms, skip all activities and boast about how many point you will be getting.
3. Talk as if you own the hall/make senseless complaints/give impressive proposals for comm and do nothing ----------in short talk big.
4. Try all means and ways to get what you want, using unscrupulous methods, resorting to backstabbing etc etc.
5. Enter someone's room uninvited (similar to barging into someone's room) in extreme cases, never even bother to knock (what have their mothers been doing????) Furthermore, sit down and complaint about personal problems, making senseless complaints about hall and go on and on with empty talks. Never fail to ignore blatant hints that they are not welcomed and will never leave the room till a sentence is mention right in their face (and despite that, he may just choose to ignore it).

However, the above will not apply (to a large extent) if you are damn shuai or damn pretty. Life is unfair isn't it?
