Dude I get it.

That's an upgrade from just laughing to yourself alone in public.

I sing 'my corona!' Which jjust adds to the embarrassment. I wish I could stop, but it's completely involuntary. I call it my form of Tourettes.

I think it's funny that the OP actually took time out to spell it.

Instead of looking bewildered and shamed from all the stares, you could say, "What, you've never heard that beat, before? What rock have you been living under??" Enjoy the scene as it unfolds. :)

You mean fetal position?

Isn't is ironic how that your method to erase embarrassment embarrasses you?

I do that too! lol

So when you say something stupid, you rectify that but saying something stupider? YDI OP! Maybe try to make things better by not making it worse.

AHAHA! i know a lot of people who do this. My friend was in an elevator with a stranger and was thinking about a guy she despises. She started muttering to herself, saying "you're so f-ing ugly, you're SO f-ing ugly". The guy was shocked and said "i'm.. sorry..O.O".
