Bacon

A ROBLOX user wearing the default male ROBLOX avatar. They could be one of three things:

A new ROBLOX user, who hasn't changed their avatar yet
A ROBLOX user, who likes the default avatar and does not want to change it
Someone on a burner account (Typically an exploiter/hacker)

They tend to be either nice, quiet, or a menace to society.

Example A:
"Hey! that bacon is hacking!"
Example B:
"Aww look at that clueless little bacon"
Example C:
"Oh wow this bacon has so much stuff"
