The 'accepted method' of eating a chick out is to spell out the alphabet with your tongue. Its not so much the letters themselves, but the strokes used to write them out. Take a look at the alphabet:

ABCDEFGHIJKLMNOPQRSTUVWXYZ

You can see that the letters are made up with a series of strokes and circles;
A: Straight up, straight down, and straight across
B: Straight up, arc down, arc down again
C: Large arc down, etc.

Start with this, then get a little creative. But remember that the only way to know how a girl likes fur-burgers eaten is to ask her.
