ADV: All Day Vape. This is a term used by vapers to signify that an eliquid flavor is suitable to be vaped all day as your main flavor. Usually more sutle tobacco flavors and not really fruity ones.
Intentional unauthorized absence from work. The term typically describes absences caused by a worker of their own free will, and usually does not refer to legitimate "excused" absences.
"Steve's not at work today, he called in a Jay-Day adv because he just didn't feel like coming in"
