Other nicknames I use for Robert Pattinson: Mr. Hunky Spunk, "Bedroom eyes, sex hair, jaw porn" and I call his crazy hair "squirrels and mousse."
Well-known nicknames for Rob include RPattz and Spunk Ransom.
Taylor Lautner is just a doll-baby, but when I'm feeling randy I call him Mr. Lautner because it makes him seem less like jail-bait.
Kristen is often referred to as KStew..
Other references for the actor/character include: Robward, Taycob, Kellett, and Jacksper
And another- I posted it elsewhere, but from Twilight Treasury, I LoVe the phrase "Rob Slobber"!
