boggle, boggling verb.
Boggle, originally used of frightened horses, is used with and without an object: the mind can boggle at something and something can boggle the mind (or the imagination etc.). The expression mind-boggling, first recorded in Punch in 1964, predates the regular transitive use, and has been joined since the 1970s by the more colloquial reduced form boggling:

• Serious damage can mean even more boggling bills —Which?, 1990

It's just boggling that they didn't decide to at least do one of these songs for the live album-music website, AmE 2005 [OEC].
