There will be no runes in this build for now. This is for lower levels, not end game. You don't buy runes until level 20 or so. This is purely for the newbie zerg of death.

We have clearly reached a point where only rampant and unchecked stabbing can save us.

When choosing starting abilities I prefer cleanse and heal. This allows you to be virtually unstoppable when chasing or running away from enemy champions. The bane of all fast hitting/life stealing builds are the stuns. You won't have Mercury's Treads, so you'll have a tough time against point click stuns and disables without cleanse.

[Riposte] needs to be pumped up asap for more AD and an excellent defense mechanism. It does a MASSIVE amount of damage and will deter enemies from targeting you at the outset, not to mention is devastating when dueling.

[Burst of Speed] will allow you to chase enemy champions or quickly down a minion wave. At by 13th level you will have 120% attack speed when using this ability. Combined with 110% from 2 Phantom Dancers and the activated 50% from Youmuu's Ghostblade, and 25% from Berserker's Greaves, you'll be attacking at 305% speed. WTF!!! Your bloodthirster(s) (or 1 BT + 1 Vampiric Scepter in most games) will ensure your invincibility with this kind of stabbing fury.

BE SURE TO ACTIVATE YOUMUU'S GHOSTBLADE!!!
You gain an additional 20% run speed and 50% attack speed. This is the only part of this build that requires any skill beyond standard face rolling. Bind this to a key you can quickly use.

[Lunge] does do some damage, but is primarily to close the gap with enemies. It has a fair range and grants a second use for free within 4 seconds. The best way I've found to use this is to [Lunge] to the enemy, activate [Burst of Speed} and then [Lunge] again. They won't have a chance to get away, since you'll be chasing after them at +7-15% movement speed from activating [Burst of Speed].

[Blade Waltz] is the grand finale of ultimate abilities. It is a completely invaluable AD Carry for group fights mid-end game. Don't leave your teammates behind! However, if a fleeing enemy champion manages to survive your daring chase, you can use this to catch up and most likely finish them off with this devastating 5-hit combo. It is best used against groups, as the damage is radically reduced for consecutive hits against a single champion (25% dmg), but is well worth it to easily finish a kill.

That's it for now. Try it out and have fun zerging! Plz vote for this build if it works out for you. GL & HF! <3
