The following guide explains how you can let rage your enemys (and allies, if you want to troll them, too).
For this you can use all champions, but teemo, master yi, etc, who have a movement speed ability are the best ones for it.
Teemo is even better cause you can stay in stealth.

First go top, bot or mid and play serious and stop if you reach level 6 (especially for master yi) and you have enough gold for at least boots of swiftness and giant's belt.
After that recall and run to one of the red points:

There you wait until you see all or at least 4 enemy champions at their lanes. If they are, just run into the base.
You should be like level 6-10 if you have the items necessairy for it, so you are able to tank the turrents for a short time. Here are the ways you can use to be only hit some times by the turrents.

Now stay at one of the blue points.
Provoque your enemys with laughing, dancing and talking. When you see that someone's coming wait until he recalled and came to you. Be careful of champs with stun or guys like teemo, who have poison.
If they are too many, damage yourself at the turrents until you got a really low amout of health. (Calculate that you have to tank the damage of the turrent to fall back from the base) Then use all your movement speed abilities, and run. If they are too slow and wanna give up, wait for them. This time they propobly aren't looking at the map, so place your teammate(s) at the special point you run into.

But you know, it's dangerous, so you need experience and skill for it.

If you just want to have fun without the matter if you loose this game or not, you (and your friend) can just run in and run out with low health without placing your teammates at a targeted place. ;)

If you want to repeat this, they perhaps won't follow you, especially if they can't see some of your teammates, so resell your items and buy the real ones, if you want to win. ;) But else, just keep trolling around. :D
Just try it, it's fun. ;D

Movement and defense runes and bla bla bla.

I just bought the best def and movement items to tank the turrents and just troll enemys in base, etc. :D

bla bla bla

bla bla bla, movement speed and so on, bla bla bla.

So, if you wanna troll enemys in their base, you need to build Movementspeed and health. O.O
