Knee-jerking is a more common term for that secondary symptom.
And boy did a section of knees jerk after Hearts' defeat to Maltese side Birkirkara - although it would be understandable if in this instance, knees were mistaken for wrists.
Yes Hearts played poorly.
Yes Hearts lost to a team that nine times out of 10 they probably would have beaten.
But hey.... shock results in football happen - even Hearts have been known to cause a few themselves.
Ask Bayern Munich.
And season 1988/89 aside, which included that Bayern win at Tynecastle, Hearts' record in Europe has been nothing short of appalling.
Even with sides that would give the current squad a damn good thrashing.
Look at the performances of Scottish clubs in Europe since Uefa created the various competitions that clubs play in and Hearts rank very low - aside from the usual suspects, Hibs, Dundee and Dunfermline also have better records than the men in maroon.
Not to say that Hearts can't improve on their solitary decent season (88/89 saw the club reach a Uefa Cup quarter-final). However, that might have to wait a year or so.
Disappointing though the result was, what was more of a comedown was the reaction of some supporters demanding that management be hung, drawn and quartered with immediate effect.
Imagine if Twitter or Jambos Kickback been around at the end of the 1981/82 season.
Hearts failed to win promotion to the top flight after a final day defeat to Motherwell at Tynecastle.
That day saw a section of the support stage a mini-riot which led to chairman Wallace Mercer having to go pitchside to calm them down.
Had the internet been in existence back then, manager Alex MacDonald's head would no doubt have been demanded on a silver platter.
I suspect Mercer would have ignored such nonsense in any case - which in fact was what he did.
Four years later, MacDonald came within seven minutes of winning the league title for Hearts.
So Ann Budge should do the same with Robbie.
One result does not a bad manager make.
Hearts' greatest ever manager, Tommy Walker, didn't have a crash-hot record in Europe himself.
Yet he is fondly (and rightly) remembered for building a side that won trophies and set goalscoring records.
That did not come overnight for him.
Alex Ferguson needed some time at Aberdeen - and even more time at Manchester United - before the good times came.
Bill Shankly took years to build Liverpool. Ditto Matt Busby at Manchester United.
Admittedly it didn't take Jock Stein long to bring glory to Celtic but you will always get an exception to the rule.
Robbie Neilson no doubt had a bad night - the worst so far in a managerial career that only began two years ago.
Unless Hearts find themselves on the verge of relegation this season, then the investment that Budge has made in Neilson should continue.
And for those fans who were moaning as if the apocalypse itself had just happened, catch yourself on.
Because Hearts have been through worse periods than losing a Europa League tie.
Ask Bryan Jackson.
