I am *not positive* but I think that is a tinted, flavored, lipglass
from the Lipglass Tasti line which is long gone and discontinued.
I think it was a Tangerine something type of name or scent.
Your best bet is to print out a nice clear picture of it and bring it into MAC so they can help you find an alternative.
If you like orange they have a wildly intense, in your face color called Morange. Just get maybe a goldenish colored gloss to top it.
