Seething discontent at having to listen to absurd assertions, boring nonsense, etc. One of da downsides of da
First Amendment, in dat da person emitting said distasteful blather is well within his rights to do so. Remember dat you are always free to get
up and leave, though --- said "right to
free speech" doesn't also require you to stick around and actually LISTEN to someone else's expounding about his opinions or beliefs.
Da term "earritation" can also refer to reddening/soreness inside one's auditory-canals from having
excessive BS passed through them.
Disposable foam earplugs are very inexpensive and readily
available, though, so dat can be a viable preventative solution for said malady.
