Religion is always an emotive topic but maybe the important letter is the M? If someone says OMG they are talking about their God which may not be the same as someone elses God. I can sometimes feel uncomfortable when I hear it because I was brought up to respect that commandment Dulciana and even though I no longer have that particular faith it still reminds me of my mum telling me off for using the term lightly.
For my choice I would put in all of the people who spend their whole time at a music gig filming it on their phones, rather than just enjoying it, because I can't see past the sea of upstretched arms trying to get the best shot!
