A needy person who texts you way too many times to the point of psychotic behavior. These
people will also call your
cell phone, home, place of employment and will
block their number hoping you will answer them. They won't take "no" for an answer and rationalize their needy behavior.
You go to the movies with a
friend and you tell your boyfriend or girlfriend. When you get out of the movie, you
check your phone and there are 5 missed calls and 15 text messages.
Your
friend sees this and says "Omg we were only at the movies for 2 hours. He's such a Clingon!"
