What is Csi'ing?
1.
The act of someone, in most cases female, seeking to see if a man is lying or already in a relationship by asking several questions of the CSI-ee and friends, looking around the apartment/house and/or online for clues like a Crime Scene Investigator.
Leah noticed a bra in a man's bathroom, dishware for two, and a photo collage of a girl in the guy's place where she has visited for the first time.
"The second she entered the house, she began CSI'ing the place."
