Even more irritating than those who have a cold and claim it's a touch of 'flu (my MIL). As if you could get a touch of 'flu!
But those who say 'oh, I've got a migraine' when they blatantly haven't. I want to say to them oh, is your sight gone? Has your stomach closed? Are you being sick or having the runs? Is the pain bad enough to warrant a doctor's visit to give you a shot of effing MORPHINE?
No?
Then it's not a migraine, fool.
And relax.
