It takes five to six drinks of an alcoholic beverage with the words "strong alcohol" in its tooltip in order to become completely smashed.

IMPORTANT: YOU MUST DO STEPS 5 THROUGH 8 IN ORDER. Also, you'll have to wait for Sraaz to respawn if he's dead.

1. Buy one of the perfumes from Lovely Merchant for 1 x  Love Token.
2. Buy  Handful of Rose Petals for 2 x  Love Token or trade with another player for the petals. ( Bouquet of Ebon Roses and  Bouquet of Red Roses will also work.)
3. Travel to Ironforge. Mage portal, tram, hearthstone, etc.
4. Find Sraaz. The dwarf patrols around the Great Forge in an approximate circle selling pies to anyone who will buy them. If you can't find him, use (without quotation marks) "/targetexact sraaz".
5. Drink the alcohol until you see a game message in your chat window stating that you are completely smashed. Pro-tip: Use the command (without quotation marks) "/console ffxGlow 0" - that's a zero, by the way. It won't keep you from slurring your speech or correct your impaired steering, but it does remove the blurry screen effect. To re-enable, just use "/console ffxGlow 1".
6. Use the perfume.
7. Target Sraaz and throw the rose petals on him.
8. Kiss him using the command "/kiss".
9. (Regret doing this in the morning.)
