The accumulation built up around a the base of a necrophiliac's penis. While this can happen when one is simply a dirty person it is most often attributed to those who engage in a necro-orgy after being in the stage of "fuck drunkenness".
Example 1 -

Necrophiliac 1: Bobby, I have been at this for far too long. We've fucked so many bodies I've got to clean up my apple pie before I get home or the wife is going to kill me. Then fuck me.
Necrophiliac 2: *vomits*

Example 2 -

Necrophiliac 1: Bobby, ya gotta clean up every once in awhile. It's been months and your apple pie is 4 inches tall now.
Necrophiliac 2: I like the way that it smells after a few weeks.

a cleverly diguised word enables you to cuss some bretherin whom you are vexed with without them realising. Apple pie meaning pie --> sigh --> sii --> simple = dopey, ditzy, not really capable of going into deep conversations in because they get lost in their own thoughts etc...
e.g ::

barney ~ oii, blad mind the-

{some bretherin falls down stairs}

barney ~ (mutters) fucking apple pie ...

Similar to "icing", if you can get someone to accept the drink apple pie, they have to get down on one knee and chug the drink. However the if the reciever pulls out a mason jar of apple pie within 5 seconds the deliverer has to chug it.
