Maggie, David McGuire, and I somehow birthed this particular insult slang on the way home from New England Webcomics Weekend last year.  I can't remember the exact mechanics as to why something lame is totally babies, nor can I remember why, exactly, babies McIntyre is a more virulent strain of babies.  Regardless, Maggie and I still use the phrase in our conversations, and when I needed a title for this storyline, describing it as so incredibly babies felt like a good fit. Apparently Robin agrees.
