An involuntary, often momentary, cessation of higher mental and/or cognizant functionality typically preceded by hearing a stops-you-dead-in-your-tracks comment (often political) or a knocks-your-socks-off experience (e.g., orgasm). Similar to mind numbing but more extreme with faster onset (i.e., it has nothing to do with the physiological response to lectures on thermodynamics).
Just to screw with my wife’s left-leaning friends and politically-affiliated solicitors, I now answer the home phone with the greeting “Palin-Bachmann 2012 campaign headquarters,” a real mindstun.
