Ok heres how you do it. You take 3 letters for example S.E.B and you make a name out of them like this:
S-stupid E-eggheaded B-Bart
But the last letter has to be a name e.g: D.E.S- the s has to be a name. then, what you do is give a person one e.g- S- A- G- Then the next person thinks of one e.g S-silly A-american G-gemma
