Simple game I just thought of, tho it probably won't last to long because there are only so many things you can do. But in this game you have to make a rhyme using the last persons name.
Example: Luggz -> Hugs
Example 2: Ren -> Pen
Etc. Etc. Etc.
So now what if they have a name like "Saberlord Scritch-n-Scratch Cakemongering The Cheat" or "Arch-Duggaknight Renacathiticus Carl Von Chezdeda'davenzki The VXXII Of Xi'a'el"
then you can go by what there best know as because most likely they'll go by a shortened name on the forums if they go by that ... well then sucks to be you ^^;
