Even though your name does look quite suspicious, I'll try to explain anyway.
The parent is showing how fuzzing works:
Using random 'data' to test the various functions of software, so we can find out if a certain piece of input triggers undesirable behavior.

But it's perhaps more an attempt at humor.
