That’s because you can’t tell apart the the thingamugjigs.
Based on the cartoon that’s not “a word that shows you’re no longer ’cool’”, that’s “a word that you clearly never understood in the first place”. A “rigmarole” is a long, rambling story or unneccessarily long and complex process that you have to go through to get something done. You could go through the rigmarole of untangling all your cords, but the tangle isn’t a rigmarole – there’s nothing to “make sense” of. And there’s nothing outdated about using it (where I live, at least); it’s merely a sign that you have a richer vocabulary than most.
(Gasp!) I just used that word in an email yesterday.
Proud to be uncool!
But is the doohickey connected to the thingamabob, or is it the whatzit?
Rigamarole is a type of spaghetti
Take it easy. Unplug them from one end and get some cable cables (there are such things) and working one at a time untangle and then connect it to the proper device and label it with the devices it is connecting ( TV – DVD/Blue Ray) and lather, rinse, repeat until you are finished.
