Nothing at all,,unless you have your own meaning behind it
No, it means you have a tattoo behind your right ear. Grow up, man.

Tattoos, of whatever location, do not actually require maintenance. The above is not true. You should care for a tattoo behind the ear like you would any other tattoo.
It means you are trendy.
you hate your date
Yes you can.
It means something to who ever has it
Yes, it is behind her right ear. It is a sixteenth note.
A Blue diamond tattoo on the right shoulder means they are a top class bodyguard, but I'm not sure about behind the ear. I'm pretty sure it means nothing unless on the shoulder.
it means "My Crazy Life"
If it's a singular lightning bolt, then it probably means next to nothing. A lot of tattoos behind the ear are completely ornamental. However, if it is two lightning bolts side by side, then it very possibly might be an SS (Schustaffen) Bolt tattoo, and is a highly White Power tattoo.
