Rules:
You start with a definition and people try to guess the word.
For example, if someone said:
[size=-1]A contest with rules to determine a winner
I would say game and give a definition of another word (once my answer was confirmed by the person who posted the definition).
Use Google’s dictionary to get your definitions (define: foo)
And, no using Google to look up answers.
I’ll start:
[/size][size=-1]Either of the two large fleshy masses of muscular tissue that form the human rump [/size]
