A phrase used by drama-prone, annoying teenage girls to describe birthday wishes from Facebook friends with whom they do not regularly interact.
Annoying girl: "ZOMG! I got so much creeper cake on my birthday!!!!!!!1111! So many creepers on my profile!!!!!1111!!
Everyone else: "People don't have to creep your profile to see that it's your birthday. If you're on their list, it pops up in their feed. They say 'Happy Birthday' and move on with their lives. Get over yourself, you annoying bitch."
