when someone acts like a cool person until the have integrated theirself and their friends into your life, then start to engage in stalker activites, such as constantly trying to talk to you and bringing up unimportant things you previously said and begging you to love them. these are ticky to deal with as if you block them and try staying away from them they will use their friend connections to find you

I was a very shy and meek kid in high school, but when I reached my 20's, I came out of my shell and became very outgoing. My friends told me that I get the sleeper award for how social I've become.

 Get the side sleepermug.
Get the side sleepermug. One of several sleeping postures best described by its namesake "Le proporzioni del corpo umano secondo Vitruvio" drawn by Leonardi da Vinci circa 1490. This resting position is the opposite of the fetal position which was popularized in French culture between the years 1859 and the present day. Most likely developed in Ireland, this "posturi vitruvio" came to an abrupt halt when eagles began tearing the nuts off of all Irishmen. Word soon reached the new colonies, and it was nearly unanimously decided that the eagle was the the most terrifying creature, subsequently adopted as our national sigil. Vitruvian sleepers will bloom best in comfortable conditions, with a solid roof to prevent talons through testicles.
Mary soon discovered that after waking up several times with a faceful of Brad's armpit hair, she was beginning to enjoy the outdoorsy taste of Gillette sport. Mary then accepted that she would live with this vitruvian sleeper for all time, and suckle the sweet residues of man dew every morning until the end of her life.
