An intellext is a thoughtful, intelligent, and generally grammatically correct text message. It is similar to "sexting" but instead of messaging about sex, one messages about smart stuff and ideas. However, the intellext can also be erotic, if the receiver or sender is into that kind of thing. It is also a statement on how our current communication culture affects what we talk about and how.
An example of an intellext might be: I got your message about the book and am glad you are enjoying it. The philosophers are singularly passionate and I find it interesting how unaware of their passion they are, with the exception perhaps of Nietzsche.
