Personality Appeal is when an individual is attracted to another person not by their beauty or body but by their personality.
"Hey Nick, did you really like Sarah? I mean she's not good looking at all"
"Fuck off dude it was personality appeal"
For some reason you find your coworkers more attractive than outsiders, and you all wear the same uniform.
Every relationship I have starts off of that uniform appeal.
The feeling of desire to try a drug because of a small amount being accidently ingested i.e. coke dust travelling into the nasal cavity and creating a desire for said drug. You get a small whiff and become addicted.
Johnny can't stop doing coke after chopping up that brick last week. He wasn't careful to cover his nose; he should have known coke has that whiff appeal.
Money is also known to have whiff appeal. You get a little and after that you cannot stop craving it.
