Basically, the term for when a guy messes a girl around. They lead you on and then come up with a big pathetic excuse or 'problem' that is so 'horrible' that they cannot tell you meaning they cannot see you anymore. they either get with an ex or with a new girl and they also say the famous line of 'i didnt mean to mess you about'. blatently did if they had said that otherwise they wouldn't know so soon that they had.

To greg someone is to ask them many questions (some would claim an unending barrage of questions) in order to suss out information and get to the root of what's really going on here. The objective of gregging someone is to gain a full understanding, or even enlightenment. There is no shame in gregging someone, especially if others are unwilling to ask the tough questions.
I decided to greg (verb) him about why he needed to buy another DeLorean given that he had owned several in the past and always ended up getting rid of them. I also gregged him on the specifics of how much it cost, why was the owner selling it, where was he going to keep it, is he buying it just to relive his youth one more time, etc... you know, the usual stuff.
