Just rant on everything that you think sucks! Even over exaggerate to make things interesting! Take for example a teacher who is lacking in some area (NO HOMO) and completely over exaggerate how terrible he is... Me and my friends always do that. For example we have a teacher who liked star trek, so we always imitate him with a really nerdy voice (not saying ST fans are nerds) and whenever we pretend we are him we ALWAYS talk about star trek, even though he only did it a couple of times.
