I don't think that J. K. Rowling would write anything like this, so as I wrote this, I'm not her, and by extension, don't own Harry Potter.
When you are drinking, you could say that you are recreating a Harry Potter series, because:
When you have a reason for celebrating and drunk some already, you start shouting things like "I buy the next round for everybody..." thinking that your credit card is Philosophers Stone, giving you infinite amount of money...
When you go to a bathroom and in some way end up in a toilet for opposite sex, but notice this when it is too late, you are inside the Chamber of Secrets...
When you finish and notice that because of the alcohol you can't open the simple lock in the door of the toilet, you are the Prisoner of Azkaban...
When you finally manage to get out and rejoin the party, and by mistake extinguish your smoke in a glass filled with a flammable drink, you create your own Goblet of Fire...
When it comes to a time that everybody had had enough, you star a meeting of the Order of the Phoenix... at earlier meeting you agreed that Club of Rainbow-like Flying Puke was too long to pronounce after couple of drinks...
If you are still able to drink, you don't really care what you are drinking, filling your glass with anything that is on the table, believing in your own mind that you are a genius at mixing potions, just like Half-Blood Prince...
When you wake up in the morning with a massive hangover, you think that anything that glows, makes any sound... exist really, is a Deathly Hallow, because whenever you have any contact wit those things, you think you can see Death itself standing before you...
AN. Again, sorry if it offends you, but I tried to warn you earlier.
Changed it to In-complete, since I'll be adding ideas as they come to me. If you have an idea of your own, PM me, or simply leave it in a review. I'll add the ones I like in here, along with the pen-name or nick of the person that proposed it.
