Step 1
Create a new document, I used 400x188. FIll it with a colour of choice and then type your text using a graffiti font(Get them here), here's what mine looks like.
Step 2
Now go into Blending options and go to gradient overlay, for the actually gradient you use double click the rectangle and you'll see the following, use the orange looking one.
So far it looks like this:
Step 3
Now i see this layer to invisible for now(You can simple move it), I then created another text layer with the exact same text but 3-5px sizes bigger, you can see what i've done below.
Step 4(final)
Now i've made the other layer visible(you can move it back now) put don't put them directly on-top of each other, move it up a few pixels to get a drop down kinda feel.
