For something to be ineffable, that something cannot be expressed in words. It seems therefore that coining the verb "to eff" involves a contradiction: it is impossible, by definition, to eff the ineffable.

The problem is that language has its limits. We can only talk about a quale (such as the experience of seeing red), we cannot use language so as to induce in the listener or reader our experience. The only way so far proposed to communicate a quale is a direct brain to brain connection.

This camp therefore proposes the term for this should be "connect", a word that has the added advantage of avoiding the slang connotations of "effing".
