A song can only have one INTRO, maybe
sciguy means a bridge or a middle eight rather than SECOND/THIRD INTRO??? An OUTRO is the ending of a track obviously, you don't have a chorus after the outro. The chorus can be the outro. Im a little confused by what sciguy posted there to be honest.
Coz is right, the stuff that really stands out breaks the generic formulas. The Neptunes and Timbaland productions are a good example of this, listen to some of their tracks.

despite what I just said lol
Get your sections sequenced and play around with the running order in song mode. You might find some unusual combinations that just work. Breaking the 8 and 16 bar mould for song sections makes a big difference if you can think outside the box, and it surprises the listener too, in a good and unexpected way.
