Dummy-o

Any generally stupid individual who solicits and receives good advice but still does some fucked up shit then has the audacity to come to you and whine about what happened.

Girlfriend: I dont know why I didnt listen to you
Boyfriend: Why what happened? ( already knowing that the answer is going to piss you off )
Girlfriend: You were right, He was trying to get into my pants...sob sob. I thought he was my friend will you forgive me.
Boyfriend: shut the fuck up dummy-o, I told you that shit would happen. Get away from me.
