To my knowledge "Greg" is Becky in her lesbionic fanfic in the honeymoon period. Thus the "hurr hurr super witty inside joke" expression“This is Greg” and points to the cheap fake llama plant. Yeah I remember when I was in middle school it was so quirky to name everything Greg and bob too! Super funny amberlynn!
Edit: I notice she really likes everything marble now for some reason.
Funny that Greg the alpaca has a long, elegant neck as opposed to BecksNo-neckster
