A person who tries to get attention by acting very depressed and is quick to take advantage of the other/any sex. (even when victim is unconcious)
Diddies are often keen to excel musically. They can be recognised by their inability to play guitar and their monotone singing

2. Do you know any one I can get off with???

3. That diddy spent all night on the stairs saying he wanted to die. everyone ignored him and it was hilarious.
