The act of calling out someone's name when they are the perfect distance so that they can hear you but they won't know who did it. This may also be
done from a car by yelling "
MA'AM' or 'SIR". When and if you get someone good it's quite hilarious. This was started in Keller,
Texas.
*Man walking down the
street* (you and your bro in your car) "
SIR" *man looks around in confusement*
your
bro says: Man, I love jaying someone up.
