Once I got hooked up with Vin and Dan and we all knew we weren't going anywhere and started with the weddings and babies storylines... we started playing more and more on the last name Wolf.
*Wolves run in packs... so came the name Wolfpack.
*Offspring of wolves are called pups... so they refer to their children as Pups.
*Wolves have mates, so instead of calling their significant other their husband or wife they refer to them as their "mate". We've also slipped in things like "just like Wolves they mate for life" when referring to their love for their mate.
Mountain Dew gave me an opportunity to use them in a little bit of character development with a limited edition flavor of Mt Dew. With just a little bit of play on the letters of her name.
I hit google and found different items that sound like they could come from a business adventure... like with the BBQ sauce.
Just a few examples of what you can do to bring more life to your character.
