"Lobe" came from an inside joke between Innie and myself. She was referencing Ferengi and thought it would be funny. I thought it was a typo and laughed. We started yelling it to each other in global because we both hang out there a lot and it stuck with a lot of Glitchen.
I guess I'm biased, but I am a huge fan of "Lobe". One might say I lobe "Lobe!"
It is just a word that some choose to use, and who cares if they do use it. Just as who cares if a person doesn't use the word. I am honestly quite flummoxed as to why this garners such strong feelings.
When I first heard it I thought it was referring to the lobes of the brain, because we're all being imagined by the Giants, like in their brains, or something, I dunno. I still prefer to think of it that way :)
Personally I think its like most (poor) internet memes and inside jokes, its funny/cute the first few times you see it but it eventually gets sickeningly annoying. Like Elle I would never willingly type it, but if someone likes using it I say more power to them.
