I was actually a regular user of GIMP for years before I learned that the word had any other definition. While working at a summer camp as a teenager, I happened to install it on an office computer. One day I'm doing some work in the office, when all of a sudden I hear one of the camp directors in the other room laugh and ask why some perverted program called "gimp" was in the list of applications.
Some classic FOSShead contrariness on their part. They shoulda used the major release to officially rename it to GNU IMP, if you ask me. GNU could use the publicity and an "imp" is definitely cuter than a "gimp".
When I was a teenager I wanted to try FreeBSD but got turned away by the daemon mascot.
I didn't want my christian conservative parents to keep berating at me as if I turned in to the devil for choosing a OS that has a mascot that resembles one.
Just don't mention the name.
