Shady

A person who promises to hangout and purpously ignores you when the time of said "hangout" was supposed to occur.

A person who tells you he has a suprise for your birthday but have to buy it yourself.

Andrew: Hey do you wanna chill tonight? Ryder Flood promised he would give a ride to us and chill on my birthday.

Friend: Yea sure!!!

Andrew: Oh wait he's not picking up his phone... obviously he is with Caitleen.

Friend: Yeah he's so shady.
