Okay, so just a quick summary of what I kind of had in mind:
Perky – 20% chance if cheerful
Snooty – 20% chance if snob, 10% chance if self-absorbed/high maintenance/materialistic/perfectionist. Maybe also less likely to get if male
Swagger – 20% if outgoing/ambitious/self-assured. 10% if hot-headed/active
Tough – 20% bro/evil. 10% hot-headed/outgoing/mean.
Goofy – 20% goofball/childish
Sluggish – 20% gloomy/lazy. 10% slob/glutton
Bouncy – 20% cheerful/goofball. 10% good
Creepy – 20% vampire, maybe adjusted based on if good/evil/mean
Feminine – if none of the above assigned 10% chance for females to get. Maybe less chance if bro/active/evil/mean/lazy/slob
