Actually, I have a lot of their friends who very casually refer to their tattos as "tramp stamps." I guess around here, or maybe it's just in the younger-ish age groups, it's a common phrase. I don't think it's any longer a reference of judgement, rather a simple reference that tells exactly the type of tattoo and it's location.
On the other hand, very easily my LEAST favorite. Waaaaaay too Jen for me. And, in my first impression/opinion, she looks and sounds like a total "I'm better than you because I'm pretty" bitch. I think she and neuro-whatever (it's all too new to remember!) Michelle are going to clash big time.
