The unmistakable scent of Mexican food that stubbornly clings to one's clothes, hair, and/or skin after dining at a Mexican restaurant. Individuals who fall victim to Mexi-glow tend to possess a 1 - 2 foot atmospheric radius of Mexican food odor around his or her person. Mexi-glow typically lasts longer than a 24 hour period before gradually wearing off; but, in some cases, it has been reported to linger on clothing for over a fortnight (particularly jackets).

Blake: A baby behind me at Avogadro's got fajitas. It's the Mexi-glow, I have it.
Michael: What a jerk.
