InterMod is nothing more then two frequencies combining together to create a third. In the process of a pair of notes that are being bent the product third will sound like it's "flipping" or "swirling" for lack of better terms as it is being moved or "bent" through that range.
Ah, but there is a word for that already! It's called "beating" and my high school band director taught us to listen for it when tuning to a reference pitch. When the beating stops, the two notes are in unison and you're done tuning.
