Bob-ter (alternatively spelled "bobter," sans the hyphen) is a high-end butter brand. It was created by Bob when he shoved popcorn into his milk glass and put it in a bucket of cheese. It is the only way to make Joecereal taste better, which is really an impressive feat if you think about it.
Bobter is currently undergoing some trials for use in other fields, such as industrial grade lubricants and hydrophobic coatings. Tanks are currently being loaded with this, because it's deadly for ants (Joe's army).
